Peavey PV-8.5C Amplifier Repair

Ok... Here's the situation... I don't know..... Should I try taking care of this myself?

[@mattmoreira210]

Generally when fuses blow, there’s something else wrong with the amplifier. I wouldn’t replace a fuse before checking the rest of the circuitry for damaged stuff, as the fuse is frequently the last thing to blow.

[@DetroitWrecker666]

This amplifier was damaged due to someone not paying attention to the speakers they hooked up to it. The good news is that after much signal tracing and diagnosis. It is up and running as it should. Turned out to be a VERY powerful amp.

[@willkupers]

Take it to the amp guy. Don't think that the (smoking)resistors are causing the problem but are the consequences of the problem. Just my wild guess. Success.

[@DBCisco]

Never use a pencil as a pointer on live electronics/electrics, the graphite is an electrical conductor. Not only can you cause shorts but are risking your life.

[@DetroitWrecker666]

This is why I used a Polish pencil. Check it out

[@DBCisco]

Yeah, Wally, I was relieved he had that one.

[@georgewocosky]

I use a Polish pencil all the time = my finger in the DIRT !

Thanks for the videos Wrecker

Dean is a bad mo fo .. I have two Marshall blues breaker clones he built for me a few years back. One is a 2 x12 combo with El34s and a set of early 70s green backs and the other is a head built off the specs from his personal 60s blues breaker head with KT 66s, I run a 2x12 cab with vintage 30s with that one but both these amps kick major ass, and for the money sound way better then the new Marshall reissued amps that are out. Both amps have tone for days .. Dean Zink is one of the best amp techs around period. Dean also just turned me on to a guitar tech in Waterford named Jeff (can’t remember last name ) I had him do a complete fret job on a old Edwards I bought off reverb and it came out super nice . I usually take my stuff to Mike Koontz in ferndale but he’s busier then hell and I was looking at a long wait time so I took Deans word for it and Jeff did a incredible job on this guitar.

Replace those small components, the small transistor and the power transistor (the one mounted to the heatsink). IDing them should be easy because you have another identical circuit on the board.

[@DetroitWrecker666]

And I just found a AWESOME website that actually has kits.... Tubesandmore.com Now I'm thinking..... I can do this. LOL! Wrecker dies on camera

[@DBCisco]

Just unplug it and wait a few days for those big caps to discharge if you don't know how to it the right way to instantly discharge them. And take pics where all the wires connect before disassembly. I learned the hard way so you don't have to. lol The soldering should be pretty easy, nice sized components. Surface mounts are for experts.

[@danbeck3166]

You got it figured ...and you re still alive watch probing even with that pencil woah use a stick I m with DB Ciscos thoughts peace out Wrecker

[@georgewocosky]

Parts are pretty cheap ; BUT there may be another problem ! * Labor & knowledge of the whole circuit could eat your lunch . . . it's a coin toss . . . 'fix the OBVIOUS' , if that fails , go to the tech ! It's always gratifying to say , " I FIXED IT ! " Rawk ON ! ** Ditto on what DB said . . . make sure the caps are DRAINED ( google it ) ' could be something as simple as a 'short' that happened on the side of the board that you CAN'T SEE ! < my guess . . . You might look for a schematic online to make it more 'visible' in your head , about how it works ! ( Go for it ! )

[@DetroitWrecker666]

Yeah, I thought it was a given about the caps and power that could be in the amplifier. But there I go again Mr presumptuous!

amigo saludos tengo un problema mi Ampliar un pv-8.5c 550was estaba funcionando lo traslade de un lado a otro y ya no funcionó y me nota el botón de reset si me pudieras orientar en la falla te agradecería mucho

[@DetroitWrecker666]

I would really appreciate it if you will translate this to English. From what I can tell, I am interested in it and I have no means of translating it.

[@DetroitWrecker666]

From what I can tell, you are asking a question regarding repair. I am not a amp tech but, I have put a link in this to a very good tech:kzbin.info/door/2DDLacv42cfgT7Urv9n3dg

What bullshit this is not a repair video this is an advertisement for a guy that repairs amps
