I found a really good fix for those conductive PCB's. I'll send you the link later. Building a Fender Champ from junk parts at the bench right now LOL

How do we know for certain that the toothbrush was invented in England? Because otherwise it would have been called a "teethbrush" :) :) :)

I seem to be experiencing this problem on the clean channel, the only temporary solution is to wiggle the volume knob which restores the volume, I just sprayed it down with electronics cleaner but from the outside and then vigorously worked the knob left and right, physically it is turning easier, give it an hour to make sure it's nice and dry, nine times out of 10 electronics cleaner it works, but I think that's more from the inside lol 🤪

Hey there...I'm having a similar problem but I'm getting sound but it's very faint....I'm getting voltages and bias is holding steady

Lucky catch with that fuse holder, and nice repair. Interesting bias adjustments on that Marshall. It's a pity all amps aren't made with that feature..Thanks for sharing..Ed..Herts..uk..😀

Putting some high temp rated dielectric grease in ribbon connectors like that helps avoid issues with them corroding over time and getting intermittent. Doesn’t stop the wear on the solder joints from movement/vibration though.

I sure could trigger a lot of Marshall diehard fans with a comment. One of my favorite rock guitarists who loves old Marshall’s and still has an old one he calls “the barbecue grill” (Phil X) when Marshall used to make great sounding amps (although their reliability was still an issue back then) decided to have another company make him a signature model. I’m not crazy about theirs either because I don’t trust mass produced PCB based amps for quality. All I can say is if you want a Marshall type amp that is a proper turret board, handwired amp at an unbelievably low price, call a gentleman named Nik. He’ll make you a lifetime amp.

Nice one. Know what I like about this amp? It's not a Peavey Classic 30 or a Fender Bassbreaker. :p

Hi you have to change c2 on the small ac input board .they fail, 022uf 630v capacitors for a hi voltage one. Again a 2000v mkp wima will do the trick

I bought one of these once. Returned it. The clean was great but the over drive was BAD! Thanks for the video.

Similar bias-measurement terminals are (internally) provided in some older solid-state Japanese hifi equipment such as Yamaha, Nakamichi and so on; the important difference being that if you short-circuit those solid-state bias-measurement terminals points by accident with your probes or jumper cables, you'll blow up the output stage in a fraction of a second (not only the "finals" as you British might say, but possibly the drivers, pre-drivers and differential amplifiers as well, plus a bunch of resistors). I made up some sets of various plug-in connectors (two-pin, three-pin, different spacing etc) with insulated leads and banana plugs on the other ends, to plug directly into the voltmeter, eliminating the need for fiddly "croc-clip" jumper leads.
@GoldSeals
Nice Video..Thanks for sharing..I have two of these amps..I have my bias settings at 90mv because 70 is too cold for my amps..They sound better at 90..I believe the schematic says a max of 90..It does seem kinda high because each tube is normally rated at 35 and two together makes 70..Thank you for your expertise..I learned a few things here.

Been having an issue with my own JCM 2000 DSL 100. One of the speaker inputs stopped working (8 ohm) so now I can't use my full stack. I have tried cleaning it with deoxit and switching cables. Also tested said cables with my other 2 amps and they work just fine.

I have a Marshall DSL 401 that started buzzing. Does it on both clean and overdrive channels and guitar plugged in or not. Are these renowned for earthing issues too, like some of the other Marshalls you've looked at? Is there a common fault?
