Hey guys,
I need to dig up this old thread. I have a couple of those 1176s and was trying to recalibrate and check them after using them for a couple of years. Lately they started to cut out here and there and sometimes there's some gainreduction happening in bypass mode.
So I started with the q bias calibration, but it seems absolutely impossible - I fed a 1kHz sine at 0dBu (0,775V), the rest is set up as should be. As soon as I turn up the input I get enormous output, more than 10V (>22dBu), so it's kinda impossible to do that setup. What am I missing there?
I really can't wrap my head around did, maybe one of you guys can help me out
Thanks and best regards,
Mathias
