The Newcomer's Forum / Transformers & Caps
February 28, 2011, 12:00:00 AM
Hey Everyone,

I had a few safety questions for SS amps. One: Do Transformers hold a charge for a long period of time (even unplugged)?

Two: Capacitors. I watched a tube repair video that showed splicing a 470ohm 1 watt resistor into a jumper clip, connecting
one side to the chassis (ground) and then touching the other side to the capacitor to drain it. Is there any reason this
information would not hold true to working on SS amps? I'm trying to get to the bottom of a problem & would like to make sure
safety comes first! :)

Thanks!

Amplifier Discussion / Noisy Solid State

Hey Everyone,
I'm new to the board, so forgive me if i should be in The Newcomer's Forum!?
I have build a few little ruby type amps based off of the LM386 chip & built/
moded a few pedals as well so I have some knowledge ::) I have a question about an old
1980-81 (I think) Randall rb-120 bass head. It started sounding distorted
and there isnt an overdrive. I'm not talking scratchy pots or high gain, it just sounds like
a fuzzy "queens of the stone age" type distortion? Someone told me it could be the capacitors?
I just don't want to replace everything on the circuit board for no reason trying to make the
problem go away....So I just wanted to know if anyone had any ideas why a SS amp might
start sounding distorted?

Thanks!!
