Thanks, more video's about testing power and output transformers would be ACE since I haven't found any on RU-vid so far! I have a Marshall 1987x that was in flood waters from hurricane Katrina. I want to test the power xformer again....I hooked it up before it dried all the way out back in 2005, and I heard some popping noises and smelled smoke! Damn it. I immediately turned off the power, and now it has definitely dried out, and I want to test it again. I have a variac.
You can run a Twin with two output tubes instead of 4 but they have to be the two inner or two outer pairs. This was done to be able to crank the amp without out peeling the paint off the walls. It still never broke up much cranked , the preamp was too clean. Good day
I'm from the bronx and moved to kentucky .. didn't understand the vib3s ..but when I sat I understood way more ...thank u for humbling me thru this time of my life...we will see u a talon on Wednesday
Bro..plz play the song first..then into teaching it..this gives ppl an understanding of what your trying to teach..your assuming everyone knows this song
I have a mint original 1973 Twin Reverb Master Volume that I converted to a head. Only about 25 hours total on the amp. Absolute Pristine inside. The head has 2- 8" Jensens for practice but sits on a Marshall 2x12 Bottom. One aged Greenback and one V-30. Both made in England. Sweet amp. Both the head and the 2x12 are in Marshall Red Tolex. I had both cabs custom made for me.
Need that 1 and 5 chord being strummed once between those lead licks. Would sound better and be more recognized by country music fans. Who aren't very knowledgeable guitarist, at this point.
I've got a 72 Super Six Reverb that I MIGHT have re-tolexed. Do y'all do that kind of work? Also, one of the speakers is disconnected, and it's the original speaker, so I'd prefer to salvage it, if possible... It may actually need the whole chassis taken out and looked at. It's getting new tubes, a fuse, and a clean up at Wilcut (in Lexington) right now. I should know more about what all it needs by, the end of the week. Would you be available to work on it, or can you recommend someone else? I don't care to drive to Cincinnati or Louisville, I just want it done right.
Really nice brother. Really nice. One of my favorite DBT tunes. The most poetic for sure. The sunnyside down and handjobs line is perfect. So is the chorus.
That was a great cover. Over the last couple years I have found his music and really enjoy it. I’m not much of a guitar player but would love to learn to play some of his songs.
Thank you! I stumbled across LJW in the Heartworn Highways documentary. The day Spotify finally put up - and kept up - all of his recorded music was a good one.
@@TheBrothaAB I created a Blaze Foley channel on Pandora. oohoopie river bottom land played on that channel, it lead me to heart worn highway. More and more of his songs began adding to the pandora channel.
Sheet music in the "Greatest Hits" tab book shows this lick an octave higher, played all on the high E and G string, which I'll notate as (G)E here, with slides as \ and / : (14)17 / (16)19 \(14)17 (12)15 (11)14 \ (9)12 7(10). I'd suggest hybrid picking with pick on the G string and middle finger on the high E. And if you listen carefully to the track you can hear the light slide between the last two octave pairs which isn't possible the way it's played in this video. Still, fun stuff either way. Thanks for the video.
I bought a pro junior used for my nephew and the guy lied about the condition when you play through it ---it is sort of whistling or howling sound wondering if you have come across this before i have searched everywhere online and there is not much about this. hoping it is just tube replacement or ...
It's hard to diagnose something in a comment section, but a bad preamp tube can cause the issue you're describing. The first step is to swap the two preamp tubes with each other. This is really just to see if you get a change. If you experience a change, we can be pretty sure that the issue is preamp tube related. If you have some spare preamp tubes, or if you want to upgrade the them to something like Groove Tubes - go ahead and change them for some new ones. If that doesn't fix your issue, take it to a qualified tech because the next step would be to open it up.
thank you i am testing tubes for microphonics first and replace tube that is not sounding right if that does not work then I will take it in to professional I appreciate you answering me.
Bought a silverface bassman last year for cheap... it's become one of the best guitar amps I ever had. So easy to work on and tweak. The only complaint I could summon up is that the chassis nuts aren't welded in place.
@@kbkman7742 All the ones I've had have been welded on. I guess over the years that really annoyed a lot of people to the extent it was a common mod. Hehe.
@@kbkman7742 , clean, rough up and degrease the metal around the mounting holes, and clean/rough-up the nuts, and glue the nuts in place with JB Weld epoxy (the slow-cure type, not JB QwikWeld). If you prep the metal well and have good gluing skills, the nuts will stay in place and won't spin when you tighten or loosen the chassis-mounting bolts. I recommend you lightly lube a quad of matching-thread bolts and put them in the nuts to keep the glue from infiltrating the threads while the glue sets.
I'm no fan of lead free solder by any means, but I've never zeroed in on it as the culprit for the issues that these amps (and the entire Hot Rod series) have with the tube PCB. I'll have to do some more research!
12at7 is your reverb driver or your PI. National made rebranded tubes in the 60’s into the 70’s, mostly sold to service shops. The 470 ohm are your screen resistors. The 1.5k are your grid stoppers. ALWAYS replace your screen resistors on a old amp like that.
Thanks for the info on the Nationals! Can you speak to their quality at all? I wish I knew the history of this amp and where it picked up just one. I'm aware that 12AT7s in Twins are used for the reverb driver and phase inverter. V6 is the PI, and I pulled a 12AT7 from that position. Someone probably moved the 12AT7 reverb driver (V3) to another position to limp the amp along.
@@TheBrothaAB , "National" tubes in a *red* box, and with the same logo in red on the tubes themselves, could have been made just about anywhere ---- they didn't make tubes, they merely re-branded them. Country of origin was shall we say "fluid", subject to change, and they may have sometimes changed the printing on the tube to say " Made in Great Britain" or "Made in Germany" to fool people into thinking they were "Mullard" or Telefunken" tubes. Sometimes the tubes were indeed high-quality American or European, but they could also be quality-control rejects, or electronics surplus, but they also rebranded some Japanese tubes as well. Originally, there was a company called National that made radio tubes going back to the late 20's and early 1930's (01A's, 2A3's and 45's and the like) and they made lots of tubes for the military during WWII, but eventually the name got bought and sold a couple of times. Not sure if it was ever the "same" company but there was a National Electronics company that was at one point owned by Richardson Electronics, who made high-quality transmitting tubes, but nothing you'd see in a guitar amp....
Been searching for a good tutorial of this one, and this is a GREAT tutorial! Now if only you can make me better at picking the correct individual string
