Hey...
The Fifty/Fifty Power Amp in my system has developed a strange noise and I'd like to hear if anyone might recognize and be able to help me ID the problem. Here are the charactistics.
For this description the amp has nothing in the input jacks - totally isolated from all components.
The volume and presence controls (which are the only controls, one L&R each) are completely off. No signal passing through the amp.
The sound is a shredding sort of noise, almost like a radio tuner signal that crackles and fluctuates but can't quite tune in. Like intermittent bursts of static.
It only comes out of the left channel.
It goes away when the Standby switch is turned off but is otherwise completely independent of the volume controls. Can't be made louder or quieter.
The level isn't obnoxiously loud and is over-ridden when I'm leaning into heavier work, but is annoying when I'm playing clean, and (of course) when the amp should be quiet.
The sound comes and goes - will be clean (gone) for several minutes then reappear with the occasional big burst, like a local electrical storm effecting radio reception.
I've recently outfitted the amp with a new round of tubes.
Does this sound familiar to anyone?
Thanks.
Cayce
