Plug a known good cable from loop send to return.
Thanks for the advice, tried it, no luck unfortunately
I even cleaned all of the jack inputs very well and checked to make sure contact points were good.Quote from: Jack1962 on June 28, 2014, 04:22:17 PM
plug into the effects loop send out to a listen amp if you can hear it most of the preamp is working , plug into the effects return with a signal source on the other end and if you have normal output thru your speakers the preamp is your problem. If the preamp test ok then problem is your power amp , the Warhead is a 300 watt amp testing the power amp can be very time consuming.
I have not tried plugging into the return of the effects loop yet, but the send into another amp works 100%; full tone, its all there. I will do the other side this evening and see if the loop works all the way to rule out the preamp. If it does end up being the power amp (which I have found something suspicious I will detail below)...I am wondering if it will even be worth it as I will have to take it to a shop. These are fairly rare, but usually go for ~$600, so not sure the work would be worth it if I can just get another one.
On a side note, I noticed 2 out of the four larger capacitors have a bulge to them on the top of the cap, one in particular is very noticeable. The circuit board with those on it is small and fairly easy to get out. If it is the capacitors, as I suspect a bulge on the top is no good, then I can replace those no problem as long as I can find replacements to spec.
I will post some pics later if that would help?
Thanks for all the help, really appreciate it.
