TFM-35 Bias Adjustment

Does anyone happen to have to know the procedure to adjust the bias for the 35? Is it 1mv? What do I connect to for the reading? :-k :-k :-k

Re: TFM-35 Bias Adjustment

No input; preheat for 5 minutes; digital volt meter +/- to TP201(L)/TP203(L); adjust VR201 until 1.00 mV (DC).
Repeat for TP202(R)/TP204(R) and adjust VR202.

TP's are on the R/L edges of the board; VR's a few inches inboard and aft of the TP's.
