Turn on static?

[Glowbug]

Hi...

I recently acquired a set of SV811-10 SET monoblocks...aside from a few minor cosmetic blemishes, they work and sound perfect.

However, I've noticed one monoblock has a tendency to snap and crackle a little when turning it on...this goes away during use, but it's bothering me a little, like something else may be up. How would I go about solving this issue?

Thanks for any help in advance.

Could be a leaky/noisy cap,or maybe a noisy (carbon comp?) resistor...
Or maybe even a noisy tube.
Kinda hard to say,But i'd bet on the caps,and/or tubes.

bad solder too...

I figured out what was going on...noisy tubes, because I swapped the tubes - sure enough, the other monoblock was noisy.

Good to know it's not the amps themselves that have an issue 🙂
