I sold some tubes and RF connectors and related parts at a hamfest to a *blind* ham radio operator who built some of his own simple equipment. The relative accompanying him to help the guy find what he needed said he could solder cleanly by painting a picture in his mind, combining hearing, time, feel and smell. I never saw any of that guy's work but I bet he soldered better than whoever butchered this Marshall.
By the time you flipped the board over, I thought I was ready for the reveal. I was not. What a nightmare! I respect your decision to stop and say “I really can’t fix this.”
Remember the six million dollar man? 'We can rebuild him. We have the technology. We can make him better than he was. Better, stronger, faster.' I'm hoping you can fix it with a new turret board.
"I've got a blowout, damper three, flight call I can't hold it she's breaking up she's breaking up"!!! A classic! Takes me back to being 12 years old in 1978 and watching this on Saturday afternoons, along with The Bionic Woman, Kung Fu, Battlestar Galactica, etc.
As for replacing with a turret board that would be a blessing in disguise. Who would be looking for a good reason to convert a PCB to turrets! Sadly it would appear this amplifier was at one time a learning experience for someone. And when I use the term "learning" I mean that in the most optimistic way. Great walk-through, thank you.
@@voxpathfinder15r , ouch! Oh snap! It does kinda look like this amp was soldered with Terry's silly "Snauzaramus" soldering iron. Actually, I own an old sheet-metal soldering iron that weighs about 5 pounds and makes Terry's iron look like a pencil ---- but mine has never seen the inside of an amplifier chassis.
A turret board is the only way to go.when you flipped that board over I said to myself no way then you gave up iI said good you would loose your mind saving that.good call bro
That's so bizarre it almost looks like whoever did that was trying to turn it into one of those "pad per hole" type builds where you draw the "traces" with solder/lengths of bare wire. I was always taught that IF you need to beef up a PCB trace it should preferably be bypassed totally (cut) and replaced by an appropriate gauge wire. But IF you absolutely need to "reinforce" a trace it DEF shouldn't just be bare wire against the board. Even if they had managed to do a good soldering job (which they clearly didn't) the "reinforcement" was actually only damaging the traces, as was stated in the video. In either case that wire needs to be insulated!
Love your channel!!! I’ve learned sooo much from you.What not to do mostly hahaha. It’s crazy what people do to these amps.They pretty much just destroy the boards.Again love your channel!!
YIKES...!!! Personally am learning much from your videos sir. Even with the limited knowledge that I still have at this point...the underside of that board just looked like a whole spool of solder was used for the connections...!!! And it looked fried...? Definitely looking forward to the new turret board 😉😎👍
19:41 LMAO!!!!!!!!!!!!!!!!!!!!!!!!! You are slowly becoming an obsession of entertainment for me. I'm not even a tech and that thing made my stomach turn. We're all shaking our heads, trust me.
Hey Lyle, do you have a favorite source for hard-to-find metric-size hardware? Bolt Depot or some other similar online source? By the way, I really miss Sears Hardware; locally, they were the best source for oddball hardware. Having cannibalized many old USA-made electronic devices, I have lots of vintage SAE hardware, but metric parts can be a little harder to find.....
you're being too kind of your description of the idiot that did this. How many more has this person done that are floating around. Doesn't bear thinking about.
@@adamhester8751 I think I got one of his masterpieces. Bought it used on ebay. Marshall jmp 2098 lead 100 solid state. At least there were only 4 small transistors involved, and some tack leads on some caps and resistors topside.
How is this possible?? One would think if you've graduated from a battery/lightbulb soldered circuit to modifying a Marshall amp, that your soldering techniques would have improved along the way!
That board is just unbelievable. I don't have any where near the knowledge or experience that you have, but I would never do something like that. If I was working on that I would ask that owner about installing a hand-wired turret board. Which I have done on a few occasions.
Lyle, I kinda, almost, hesitated to open the video. Two videos in one day on the same vintage amp with a "WTF" in the title? Ominous omen But like seeing a car stuck on R/R tracks 20 seconds from meeting a mile long freight train doing 60 there was no way I couldn't watch. Man, what a "goat fornication" to have been perpetrated against a classic amp.
It's a ghost train for electrons, maybe a futuristic version of a flea circus. I think musical electrons prefer an exciting but solidly built roller coaster : )
To be fair that sums up most vintage amps at this point. They are either played to death and there's not much left cept the iron or they are museum pieces and have no soul.
@@PsionicAudio Why continue with those solder-suckers? Get yourself an electric one, such as this one: American HAKKO Products FR301-03/P Desoldering Tool 4.9 out of 5 stars 129 ratings List Price: $309.97 Price: $245.00
Would you consider in your own time slowly fixing all those traces to see if you can get that board working again? Or just not worth it? Maybe like a project sticking it into a line 6 combo amp?
@@PsionicAudio must be annoying for lots of techs! Whenever I have a business, no matter what I do - I can never get high rolling customers and end up working within extreme budgets. I could never spend the time you do unless I valued my work at $10/hr. If I worked on that amp, I would be making quick fixes and nothing would work because of all the butchery.
DIY Layout Creator, Corel Draw 19, Express PCB, and Ltspice. Plus lots of spreadsheets I've made that do tricky math for me. And #2 pencils and a ruler for load lines...
Is there a certain type or brand of carbon comp resistors you use for replacing on older Marshalls or building a kit? Thought I remember you saying something about the hardwired vox models have crappy carbon comps...
Trash that board! It's beyond saving, put in a turret board. This is why amp techs get a bad name, there are quite a few "techs" that have no business servicing an amp. They fuck it up for the good techs and everyone else. All I can say is, "WOW!"
I'm not even a tech but rebuilt several amps that looked and sounded awesome. This looks like a 5 year old got inside there and destroyed this beautiful piece of history. WTF is right!
Wow, that board has been butchered to the point it's not original anyway, might as well get a replacement reproduction board. I've never seen such an atrocity in my entire life. That's what you get when you let Charles Manson "fix" your amp, "Helter Skelter".
