Ok, you guys talked me out of working on it myself.

Right now what is wrong with the amp is the following.

1) Right side channel (looking at the amps front) is blown, both inputs.
2) The left side channel's volume will not go all the way to 0 volume output. Still is fair amount of output. Then goes loud very quickly.
3) Lots of hum.


Other than those three things, what are some things you all think I should have looked at/replaced while it's there?

I was thinking caps? I've heard that caps go bad after a while. if so, would it be recommeded to stay with original specs and type or would you guys suggest other values and type.


I'm looking for 80's rock tones out of this amp. Van Halen, AC/DC, Dokken, Tesla.... Granted, I'm sure all those guys used tube amps...

One thing I noticed with this amp, when I used my tube screamer pedal, it has a very brittish sound to it, I personally don't favor that brittish sound, rather have a more modern sound.

I'd like it to have some nice rich highs, nice mids, and meaty chunkie lows should I want them.



Anyway, any help with what I should have him look at while it's at the shop would be great!


Rick

I got my amp back today. Seems to play well. both channels work now and both inputs on each channel work great. I haven't had a chance to really play much with it, but should be able to tomorrow.

Nope, but inputs on both channels are working and no hum... Sounds nice and quiet.

Hi, and thank you of the schematic.
other than clean tones oyu wil not get the type of sounds( ac/dc and such) out ofthat amp with out some type of digital modeling pedal, up loud they will give a pretty good crunch but thats about it.

When I think '80s Metal, I think pretty severely scooped mids (not just turning the mids WAY down, but boosting the bass and treble at the same time) and solidstate Randalls or valvestate Marshalls, rather than a tube-emulating stompbox into a tube amp. If I were you, I'd try putting a ProCo Rat in front of that Kustom and see what happens.
