This year I didnt get any of my planted vegi's because the squirrels ate everything. In 20 years prior I never had a problem but this year they took over... Next year I'll have an electric fence.
I used hardware cloth and an electric fence and have something eating my tomatoes. I saw a vole in the garden. Plus I have one of those vole sound thing that clicks. It’s very disappointing
Turns out my GE7 is from the early 80s and needs the ASA. I don't remember owning the original Boss PSU, but apparently now I do. Might have been a mix up years ago, because these power supplies look very similar
Man, I've been banging my head against the wall on a trace elliott 7 band eq I got from Goodwill. Would not come on for nothing! And your advice on the power jack was spot on. I tested the jack, and it wasn't crossing over to let the battery work. Took out the jack and soldered the pads across on the board for a test, and the leds kicked on! Thank you Sir!!!!!
Hey james, I have boss BD-2 as well, in another video you said boss doesn't sell parts anymore, I need to get a new dc power jack for the pedal. I do not know how to find the part number and I wanna make sure I order the right part. Where can I find the right part and or part number? Another concern is the pedal has the revised smaller circuit boards (I bought it brand new inn 2021) and it seems too have a slightly different DC power jack (I could be wrong about it being different), but this is why I wanna make sure I find the right part.
Hello James, I never seen the base of the reverb tank like that with wood shims. Are all fender pre cbs reverb tanks like that with the wood and cardboard? thanks for your videos....
Hi James, thanks for the video! I got a boss equalizer that works when you plug the battery and also sound works when on power source. But the led goes off when at power source and lights on when on battery. Any clue how to fix it? Thanks a lot!
I have an old Crate B10 xl solid state amp that I’ve been trying to get working again for a couple years. There isn’t any repair places near me and I searched all over online with no luck finding any similar problems like mine. I was playing it and all of a sudden zero audio, not even a hum, the fuse wasn’t blown and it still powers on. I’ve confirmed that the speaker is still good, I can’t see any signs of something that got hot or blew, the jack inputs are making contact and are re-soldered, all of the wiring is good, and it doesn’t even make a sound when I touch the aux jack.
You say you checked the input jacks, but have you cleaned/checked the headphones jack? That jack can cause loss of audio if the normally closed contacts are dirty or not in contact. You could also plug in headphones and see if you have sound in the headphones. If no sound at headphone or line out then, possibly one of the two Integrated Circuit components. Diagnosing those are advanced troubleshooting. Start with the headphone Jack and report back.
Heres MY situation. Peavey XXL head Solid state ..... I kept getting weaker & weaker signal, almost like a bad cord or something .... Swicthed cords , tapped dials, tapped guitar, plugged straight into head with nothing else ... same problem signal getting weaker & woukld eventually come back up. .... Come to find out I had my Amp on 8ohms, but the cabinet is drawing 13.2ohms .so cab SHOULDVE been on 16 but it wasnt, it was on 8ohms. . Thinking I burned up something, plugged patch cable into effects loop on a whim ...........& the amp plays fine. Unplug the cable & it is back to fluctuating up & down again. ......would you still think its the input jacks for the effects loop?????
Sounds like you’ve determined the power amp section is ok. The problem is between the input jack where you plug in your guitar and the effects loop jacks. So, it still could be the effects loop jacks, but could also be any other component in the preamp section. I wish I could tell you where you’re losing signal, but that will take some advanced troubleshooting.
@@jamelectronics unplugged it, flooded the effects loop jacks, plugged the cord in and out 20ish times, floooded some more...... repeated , waited 20 minutes, played it, problem solved. Fixed, thanx to this video.
To really get the cleaner into the pot, the board has to be raised. However, you can remove the knobs and spray around the pot shaft and then rotate the pot back and forth. This often lets enough contact cleaner ooze down into the Pot to clear it.
Wrong mindset. Simply grow more and be happy watching the quirrels snack. If plentifull tomatoes they leave some for you. It's like squirrels eat tomatoes, squirrels happy. You watch squirrels snack, you happy. Plant more tomatoes, sell some, ur both happy. If the abundance of squirrels is too great, catch (a few, not all) and sell some, more people happy.
My man, you just gained a subscriber. Wow...I've been fighting this one for a couple of days and was getting ready to take it in. Found your video and it's been playing absolutely clean for about 45 minutes now. Thank you!!!
If you’re asking which should be used for amp biasing, you could use either. If you are using a calculator such as tedweber.com, they use cathode current. Someone else’s calculator might use plate current. Cathode current is easier to measure since you are dealing with lower voltages in the cathode circuit. If you measure cathode current but want to know plate current, you can subtract the screen grid current from the cathode current to get the plate current value. To get the screen grid current, measure the voltage drop across the screen grid resistor, divide by the value of the screen grid resistor and there you have it.
@@jamelectronics Yes, thanks so much....I'm slowly learning, I used to bias my amps but years and years ago and perhaps incomplete understanding...thank you for sharing
Hello. I have a Harley Benton GA5 guitar amp into which I would like to build in a spring reverb. Which I'll take from an old Laney PL50 Reverb Can you tell me where to attach it according to the diagram? I want to build it into the body and mix in the sound of reverb.
Hey man I have a line 6 amp that when I first plug in my guitar and power it on all the effects and knobs seem like they're turned up way high. I have to turn each knob and then it goes down to a normal tone what do you think that problem could be. Please and thank you
The most critical connection made, from the 2 1k ohms , is absolutely confusing. Did you solder? Exactly where are the 2 resistors soldered to? Jerky video, thumb blocking, and no schematic drawing, pointing, exactly, where all connections are made.
@@jamelectronics Couldn't seem to take constructive objective critiquing? Hope you will inprove. Moved on nicely, by the way, after doing more research.😑
@@user-no9qn5gz8w, Bobby, I made this video 7 years ago. I apologize if my video quality is not up to your standards. So sorry about the shakiness, but my intention with my videos is only to give information about things I know about to those that would like to watch. There is the schematic drawing at 1:35 in the video that you said I should have included. As to soldering, it looks plain to me in the video that the connections are soldered but, they can be connected without soldering - it's the viewer's choice. I don't think my finger is blocking anything. The circuit is so simple. Only 2 components and a schematic to show what connects to what. Did you not see the schematic? I watch a lot of DIY videos. When I am doing a project that I need to know how to do, I watch several RU-vid videos. Some contain all the info I need, and some do not. I never critique someone else's video. They've taken the time to present something they believe will help someone else. I don't have the time and besides what's the purpose- they are not going to make a new video "fixing" the things I have pointed out. They're offering a video, and I can watch or not. By watching multiple ones, I get a very good idea of how to proceed. You "moving on" to do more "research" is a good thing. I'm sure you learned a lot. Good luck on your future pursuits!
Can I use it in Bluetooth decoder which has left and right connected to mono amplifier.....when I connect only right and ground it's sounds like...static fm the clarity of music does not clear at all do you think that's the reason
Some people think it is better to use two tubes that are not perfectly balanced. And I am a fan of 5881's in Fender amps. To my ear, they have a cleaner, tighter bottom end. The current Tung-Sols seem to be good.
My Randall rbx500 was having a volume drop issue. Watched this did the cable trick, which worked after some giggling. Really annoying, it's still not 100% reliable, I think I'm going to have to get it removed as I will never use it. Really dumb idea fx loops. Thanks for the video
A tip for you when setting out plants, for example tomato plants. Drive a piece of rebar in the ground beside your plants' take a piece of copper wire and conect it from rebar to rebar in series. Take a car battery and a set of jumper cables and connect the ground to one of the pieces of rebar or the copper wire' take the hot cable and touch it to the copper wire or one of the pieces of rebar for about 5/10 seconds. The worms in the ground will get excited and wiggle around, causing an under ground tillin effect. That will help the roots expand and the plants will grow faster. Most of the worms will come to the top of the ground' you can catch a few and use them to go fishing and have fish and tomato sandwiches.
Hi James, thank you for your videos, I'm gonna pass this by you just in case... I have a JCM 2000, English 100w head, (2005 post bias drift), just purchased off the Internet, I just re-tubed it but it still sounds like it has a cool bias setting even though I have it set hot (88mV, Marshall recommends 90), I tried cleaning the effects loop, patching it but to no avail... Something I just noticed is, if I tap on the master volume knob it won't completely mute when I have it on 0, if I keep tapping it goes away (completely mute), and comes back so naturally I stop tapping when it's muted (normal), ever come across anything like this?
I would use contact cleaner on the volume potentiometer if you haven’t already. Even turning the knob to 10 and back to 0 multiple times will sometimes clear any buildup inside the pot.
Your “yellow” chord solution doesn’t work for my blackstar ht club 50 low volume issue. I can’t run my delay through the effects loop if I’m using your “yellow” chord trick. I never had this low volume issue till I bought a delay pedal and ran it through the effects loop. It’s definitely an effects loop issue. I opened a trouble tkt with Blackstar, no doubt they’ll know what the issue is. I just hope they will to tell me and that it can be fixed. You at least helped me isolate the issue. Thank you.
Update. I spoke to an local amp repair guy. He explained this cable truck you were talking. I’m using that technique now to see if this rules out my amp or my delay pedal. He said that he has seen where the delay pedal can cause the low volume issue. I’ll follow up.
Solved my problem too. Thanks James. Was trying to get two old Boss peddles to work from a multi power supply. It has 8 x 9V and 2 x switchable 9-12-18V. Guess which two suddenly made them work on 12V,,, Here was me thinking I need to replace an CE-2 and a DM-3
can i do the same cable patch method on the power amp input and output.?? ...Edited comment well i did the patch on the effects loops i just bought an ampeg VH-140C for 100 bucks the owner stated on the sale add the volume cut off i tell him I'll take it maybe i can fix it i did a throughly clean-up but the problems did not get fixed with the volume cutting off on the high and low channel even one of the speakers wasn't getting signal out weird that i use a effects modeler on the efffect loop input and i switch it to preamp input to and it work fine i was watching videos about fx loop and came across this one and i did exactly this i patch the effects loops and voila problem fixed thank you very much
Great video. I have a Crate XT15R...got off Craigslist free came with free Japanese LP with broken headstock. Repaired guitar...re-strung...Amp only worked through headphones. :( After watching your video, I removed the amp from the case and was able to clean the contacts in headphone and speaker jacks (I used some tweezers to wiggle and drag thin strip of fine sandpaper between the contacts). Works like new! Video inspired me to get at the jacks!
@@jamelectronicswhen using a non-contact voltage detector, the wires coming from my power switch to the fuse box at the back there are hot. The red and green wires coming out get nothing. Does that suggest an issue with the fuse(s)? I don’t see an easy way to replace them on this unit. (Crate gfx15 looks really similar to your on the inside) Any experience with this?
There are 3 wires coming into the amp from the power cord. The "hot" wire goes to the on/off switch and then to the transformer. The transformer is mounted on the back of the chassis (could this be what you think is a fuse block?). The 2nd wire goes straight to the transformer and is the Neutral wire. It will not show any voltage with your probe. The 3rd wire is a ground and is terminated directly to the chassis and is a safety ground and obviously has no voltage. I don't believe there is a fuse in your amp. Not sure what your issue is with the amp, but I hope this helps.
@@jamelectronics oh I think what I was calling a fuse box is the transformer. So, should the red and green wires coming out the bottom going to the board be hot?
Thank you so much for this video!! I've spent months trying to figure out what could be the issue and finally it worked like magic! I was just about ready to throw my amp out the window as the local tech could not remedy it. Thank you!!
What if the volume fade-out is NOT solved by the patch cable from Preamp Out to Poweramp In? My brother has a Peavey Artist VT hybrid combo amp and it's volume always drops about 30 dB after it's been operating for about 10 minutes. It does the same fading when the Preamp Out of a second (good) amp is cabled to the sick amp's Poweramp In jack... a setup intended to test the sick amp's poweramp module. (Note: The Preamp Out jack of the sick amp was also cabled to the Poweramp In of the good amp during this test, but that pair wasn't being driven by the input signal.) Does this imply the jacks' internal connectors are NOT responsible for the fading? The four output tubes appear to glow orange as steadily after the volume fades as before. If the fadeout might be tube-related, could that be tested by removing two of the four tubes? And then reinstalling those two and removing the other two? Or does the amp require all four tubes to be present to work at all?
