I had this on my other "Kustom Repairman" post but thought I should start a new one since I've decided to try to fix it myself, with a lit'l help from my friends! lol.
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!
