Hi, I live in the Northeast Maryland (Belair) area,any good techs that can fix my A-4 near by? I think the last storm we had a lightning strike and it blew cable boxes washing machine and worst of all my beautiful sounding Kustom A-4. Any help would be greatly appreciated, thanks!

I don't know of anyone in your area, maybe one of the others here does. What is wrong with the amp?

The 1st channel (effects channel) is totally dead, the 2nd channel works perfectly so there is power. Also its strange, If I tap lightly on any of the knobs there is a loud pop. I took the chassis out and there doesn't appear to be any burnt areas on any the circuit boards, no lose wires etc so not sure where to begin.

OK, I have this A-4 out of its cab and I'm checking around being very careful not to get electrocuted and not to mess anything else up. But with it plugged into a speaker cab and turned up I was tapping lightly on some of the caps and there is a static pop when I tap 4 of the white Malory caps at the top of PC boards 103 on both sides of the amp 2 are 25MFD 35VDC the other 2 longer ones are 100MFD 15VDC. I have another A-4 that I can compare with and works properly (just doesn't sound as good, lol)but it doesn't make the pop noise when I tap the same caps on that amp. So, I guess I'm wondering if this is familiar to anyone? I would really appreciate any input. I've been on CL and all over the internet doesn't appear to be any tech close to me, I'm pretty handy and I'd love to keep this amp working so.....thnx!
