TUBE PRES

Post by audioaudioaudio » Sat Jan 22, 2005 8:53 am

Nothing like vox distorted by tubes.

I'm new to electronics, but I've been working on a clone of an Altec 1566A. I'm at an impasse. Please advise if you can help:

It oscillates (& hums, but I think that's a side issue) and no audio will pass--except over a small range of levels dialed in on the volume control. What could possibly be causing this?

Bad fiilter caps, perhaps.

I'd have to stick it on the bench to see.
