- Welcome to the plague doctor channel. In this video I go through and repair a vintage1970’s era peavey “The Bass”. This amp needed new electrolytic caps, output transistors, and some preamp issues.
Thank you for bringing my ancient gear back to life!! Meticulous and thorough work paid off for sure, it's nice to play through it for the "old guy rock" as my son calls it. Thanks a million times, Ben!!
Good job! It makes me happy to see old things brought back to life. Keep up the good work!
Hello, I bought the same amp as yours but I notice that it distorts on the normal channel once warm? Can you help me please. Thank you
I just got a 400 series and may I ask where you got the 60142 replacements?? Thanks in advance..
Just took my almost non functioning 70's Peavey Musician 400 head into a local, very old, audio tech guy/genius.........$90 kiwi bux l8r and it's ready to crank out wallz of deafness for another 50 years- u amp doctorz R O C K!😁🤘
Another "excellent used amp" from GC. Good job bringing it back to life, but it should have been repaired before selling it to a customer.
I swear there will only be two things left alive at the end of times; cockroaches and Peavey amps....
Good job!
You probably already know; but beware of 'good deals' on ANY transistors. Lot of phony transistors floating around. Always safer to pay the extra price and buy from a reputable outfit, like Mouser, Digikey, Jameco, etc. I have risked it and bought IC's from China and most were good. But transistors seem to be the focus of scammers selling fake parts.
May God bless you and watch over you.
Thank you for the input. I got them from another amp tech here in America who had bought out an old electronics supply store. He happened to have 14 nos transistors. I bought 10. Im always aware of fake parts and usually only buy from digikey or mouser, depending on who has the best prices or particular parts i need from that order.
Hello what transistor replacements did you use in the preamp section ?
I have an 800 series amp super festival series 800-g that i got when i was 15 i have schematics on everything but the foot switch. have you ever figured that out? thanks
Thank you. My friend just inherited a vintage 1971 Peavey 300 bass amp with an additional standard head. Unfortunately he is experiencing unwanted distortion regardless of the input jack or head used. He suspects the previous owner may have modified something in order to produce a constant distortion. I would greatly appreciate your thoughts/comments on how he could get his amp working as designed, i.e., no distortion. Thanks and Semper Fi - Ken
I would suspect the electrolytic capacitors first. Old electronics can have all kinds of issues from bad components, to things being out of tolerance or dirty.
Outstanding and my thoughts exactly@@plaguedoctoramplification7841 However my friend thinks the previous owner modified the amp in some fashion. To me, distortion equals an increase in voltage or current driving the power amp. As an aside I have a 1970 Fender Twin that had the old paper wrapped capacitors in the power supply. I knew one was bad but replaced all of them and it resolved the issue. In any event, thank you Sir
@@greyfiit’s possible. But I wouldn’t jump to that conclusion unless the previous owner said that’s what they did. It’s more likely there’s a problem.
Dang just bought one at Guitar Center myself hope it works at home.Sounded like a wounded lion at the store holy stoner metal Batman.
Hope it works out for you. The one i repaired armed to be stored in a barn for a while which never helps electronics.
@@plaguedoctoramplification7841 Is the distortion footswiichable? Asking for a fiend.
I got 3 bad heads from guitar center in a row. Funny how when I trade in they make sure to check every detail but when I buy it feels like they say "Hey It Doesn't Smell Like Cat Pee So Let's Not Test It And List It As Great Condition".
Que trancistores yeba todos iguales numero
