Hello folks, I have a problem on an La2a that I have not been able to track down yet and, was wondering if someone might have a clue or tip that could help me resolve this. Here is some info.
All the voltages at the standard test points on the schematic / tube sockets appear normal. What's happening is the VU meter starts to flutter back on forth when the gain pot is turned. I think I'll change the pot because I just noticed that you dont even have to turn the pot to trigger this fluttering. Just snapping it with the finger can also cause it to flutter.
As you may know I've built about six of these so far and have had only one that had a ground problem. So I'm scratching my head. Off to change that pot now.
Nope, not the pot. Thought I found it. Still flutters.
Thanks, ~R
