JMF Spectra 30-T Sound Drop Out
The drop out issue starts after about 5-7 minutes of the amp being on and played. The sound doesn’t die out, it just fades and crackles, then comes back on after a few seconds. This repeats every minute or two. QUESTION: is this most likely due to old (35 years or so, I believe they are original) filter capacitors, and replacement of those is a likely fix? I’ve fully retubed, that didn’t work, I’ve cleaned the send/receive jacks, that didn’t work, I’ve look over the board and found one little plug that was a bit unseated and fully reseated it, that didn’t work. So now I’m suspecting it needs a recap. Does the sound issue sound consistent with failing caps? Many thanks.
