Silvertone: Fix problem or overhaul?
45 year old Silvertone 1484 crackles loudly when bumped or when vibrating at higher volumes. Crackle comes with a hint of reverb, although reverb not working. That model's reverb supposedly doesn't sound so good anyway, so unless it is the problem, I don't intend to fix it.
One tech says if I intend to play out or record, it'd be best to give it a thorough going over, replacing caps and other items. He says it could be anything. Another tech thinks he can fix the problem and isn't recommending an overhaul. Neither have actually seen the amp.
The amp is a gem and could become my number 1, if reliable. Any downside to an overhaul, other than what could be several hundred dollars in cost? On the other hand, I could probably fix the crackle for a fraction of that cost and take my chances. I did reseat the tubes and that didn't help. Any other ideas?
