Alex, Yes, I did mean "Alex."? :) Yes, your VGA bracket came out looking like a machine stamped insert.? My big concern is that from certain look angles it might make it hard to see. Where did you

Hi William, It sounds like the problem is with one of your audio boards. I would swap the Audio analyzer #1, #2 and modulation distribution boards and see if your problems go away. We have a lot of

Thanks Rick, I suppose that's $US + Wads more for USPS.? Always a problem for OZ. We are more part of Asia, but most of their stuff is consumer quality. I have been reading the manuals from IO
