Bride of Zen setup help...

rtate · 8th July 2008, 06:47 PM

I just got a bride of zen and i would like to make sure that it is set up properly as it has been in storage for awhile.
I can't seem to find any documents that will tell me where and what to measure for the pot set up.

Can someone help me out??
Thanks...

I see that adjusting the bias to 40ma is done by adjusting P102 to get 4v across R108.

How should I set up P101??

Forget I said that, I realize that p101 is the volume control...duh!!

I measured approx 3.6v across R108 so my bias is slightly abpve the 40ma, Is that correct??
I have read other places that the bias should be set lower to reduce clipping, somewhere around 29-32ma and needs to be set with a scope which I don't have.
If this is the case what would the voltage drop across R108 be to get 30ma??
