|
|
Hi,
I'm trying to do the tube bias adjustment on an ESX1. I have the stereo-to-mono mixing cable setup using alligator clips and 1/2w resistors. When I run the diagnostic program, the number it displays changes about once a second. it almost never drops below 0010, and when it does it is only for a second. Changing the pot changes the range of of numbers it jumps between but nothing is ever steady.
What is going on?

Gotta respect your dedication, I've only ever "eyeballed" (read: didn't care too much about) the calibration. I pretty much glazed over when you started talking about alligator clips; I don't even know the procedure! Sorry I can't provide any insight, but hopefully you figure this out. Maybe it's normal to have some variance...? |

Yeah, I've just been rehabbing this machine and want to get it back to factory spec. It got beat up in shipping and I had to replace a bunch of the front panel controls, and track down a capacitor with a broken leg. Now there's this issue and it makes me think there's something else internal going on that I haven't found yet.
