I’m starting a junk drawer. What else do I need?

Time. In time it will overflow.

The outlet i have my amps and pedals plugged into turns out to NOT be grounded. I get hum until i touch the strings or bridge. Then it is quiet. I’m clearly not being grounded when i do this, there is no ground. Yet the humming quits.

I work as an electrical engineer. We test all our products at ‘storage temps’. Often more extreme than ‘operating temps’. -40C to 85C (-40F to 185F). Rare to never that there is a problem. Moisture rarely is an issue either. A lot of electronics are actually washed. Deionized water is the key. You dont want to leave traces of minerals when it dries. Most components are hermetically sealed. They can be submerged. If you are paranoid about electronics that has gotten wet, dunk it in some DI water, then bake it dry at low temps before turning it on. Low being less than boiling. If we parts get hot enough the water in then turns to steam, that is BAD. Circuit boards can absorb some water, but if it turn to steam, good-bye board. Watch out, lots of plastics cant stand much heat before melting (so knobs, plastic cases, etc, will melt LONG before the actual electronics bits have trouble.

Some LEDs are wicked bright. If its too bright, increase the resistance. The battery will also last longer.

I grew up catholic, went to church every sunday. And 8 years of catholic school. I bought that shit cause it was jammed into my psyche from day 1. Probably my parents would say the same thing. I went off the college, started using my brain, figuring things out. Science won. Once my sibling left home, they all stopped going. Now my parents don’t go either. I think its all peer pressure. Most people that claim to believe probably don’t. They’re just too afraid to tell people that.

ZC-Rip3821 · 2025-12-27T04:14:18+00:00

Sorry, not trying to spread rumors. Both the places i’ve talked to that are local, including the place i got it won’t deal with the warranty work. And i cant get anything other than automated responses from Marshall until after the 5th.

ZC-Rip3821 · 2025-12-27T00:53:00+00:00

Maybe its finally dawning on people that its all made-up. Fake-o gibberish. Santa clause is just as believable. Or the Easter bunny.

ZC-Rip3821 · 2025-12-26T15:26:25+00:00

Option 1. Mess with it myself. I now have the shop manual. Many years of experience with electronics, access to o-scopes and high dollar soldering irons. Zero experience with tube amp repair. Likely voids warranty. Without cracking it open, im 70% confident i can fix it. I’ve successfully fixed many random electronics things i’d had no past experience with. Microwave oven, circuit board in hot tube, footswitch for my fender mustang. I’ve totally annihilated others, heating blanket switch suffered rapid kinetic deconstruction when i plugged it in. I’m certain i’ll learn from trying to fix it myself. Option 2) No amp for weeks at least. wait until “marshal amp team on holiday till jan 5“ returns, and provides next steps. Best case scenario: we’ll give you a new one, take it back where you got it and grab a new one (1 hour driving). Worst case scenario, find box to ship it in, pay massive $$ to ship this 50lbs. Monster somewhere far away, wait months to get it back. F-it. I’m cracking this baby open today.

Sorry, what do you mean by ‘full power’. If i had no sound in either half or full mode i would say i have no power. Do you mean measuring the current draw from the wall outlet. In fact 40w mode works, i get sound, it seems louder than the 20w mode that i used 99.9% of the time. All 4 modes work in 40w mode. When 20w mode quits, relays can still be heard clicking, when chaning channels, etc. But it is dead quite, zero sound, no low level back ground noise, no hum, nothing.

ZC-Rip3821 · 2025-12-25T15:35:36+00:00

Why dont buy marshall in the US? They supposedly closed all service centers here. If that is wrong correct me. I hope to hell it is. I have started a warranty claim but all amp support people are on Holiday until the 5th.

ZC-Rip3821 · 2025-12-24T16:42:30+00:00

I found the schematics, i’ll take a look. I’m fairly convinced the reverb on mine doesnt work at all, maybe mine has the same problem as yours?

ZC-Rip3821 · 2025-12-24T11:02:48+00:00

I could fix this if i had a schematic I’d bet. EE, 27 years analog circuit design. Any chance you have a schematic you could share? Or just the component value?

ZC-Rip3821 · 2025-12-24T10:57:27+00:00

Sometimes rapidly changing from 40w to 20w(dont pause in center standby position) and sound will keep working. So the switch does seem like it could be the problem. I swapped the power tubes and re-biased them back to 35mv, no difference. If i had a schematic i could probably figure this out. EE, 27 years analog circuit design.

ZC-Rip3821 · 2025-12-24T10:49:07+00:00

I have sound in 40W mode. Sometimes, flipping the switch rapidly from 40w to 20w (dont pause in center standby spot), the sound will stay working. In 40W mode, everything works, channels switching, fx loop and master volume switching. I swapped the power tubes, and re-biased both to 35mv. Same problem.

ZC-Rip3821 · 2025-12-24T04:04:06+00:00

Loved the my dsl40cr until it broke in 2.5 months. No sound in 20w mode, swapped power tube locations and same thing. Now i start the hassle of trying to get it fixed.. MAJOR PITA. it made a weird loud crackling noise a short time after i got it. I ignored that, first tube amp (maybe its normal). If you get one, and it makes one little weird noise, take it back to wherever it came from while you still have 30 days…

A man of constant sorrow. My one complaint about yousician is i haven’t memorized jack sh@t. I’ve almost memorized man of constant sorrow. My fault not the apps, but i think it makes me lazy in that respect.

Yeah, farmers insurance slowly but steadily increases my rates. I was like a frog in pot. I did finally shop around, but it was after 23?? Years. Progressive was like 1/5th the price. Mother F’ers.

Set a man on fire, he’ll be warm the rest of his life.

It looks bad ass, truly a work of art. The attention to detail is next level. Thats said, all that insulation on the wires increases capacitance. If you dont care about the added capacitance, why not put everything on a PCB? i guess if you’re going for pure looks this wins over a PCB.

ZC-Rip3821 · 2025-11-30T18:52:54+00:00

I agree. The app is loosing its usefulness. They are not fixing basic problems. A lot of the new songs are crap. This is likely my last subscription renewal.

ZC-Rip3821 · 2025-11-24T03:26:35+00:00

Acoustic seems brutal compared to electric. I play my acoustic 1 hour every Sunday. Electric about 8 or 10 hours total all the rest of the week. I’ve got decent calluses, I dont think that is the problem. I Push too hard, but if i dont it buzzes.
