Hello Everyone,
I'm working on an 1176 clone using mnats’ revision J board and the BOM from Greg.
After initial power up I had input a signal and the meter would respond, however there was not output. Then I attempted the calibration using the instructions on Gyraf’s site (without a scope as I don’t have one) and now I get the signal to pass through but it's not compressing (or at least doesn’t sound like it) nor does the meter move with input.
Even the zero adjust pot has no effect on the meter. Although the needle on the meter returns to -20dB in VU mode, it stays at -7dB in GR mode. It also pegs for a instant once in a while when the unit is initially turned on.
I’m using the transformer input and wired a dpdt switch to enable the "all buttons in" function using Gyraf’s notes. The ‘all buttons in’ switch seems to compress for half of a second when switched on but then goes back to no compression.
Can anyone help? At least point me in the right direction? Do you think this is more of a calibration issue or is there something else I should be looking at? I can send pictures if that helps.
Thanks so much for any help.
Robert
