hifijedi 4 Posted May 7, 2023 Posted May 7, 2023 I would like to know if anyone knows the procedure for adjusting the bias and offset on a TFM-55 amplifier? I have the schematic but can not figure out where to hook the leads and such. Please help 4
itchitch 4,651 Posted May 7, 2023 Posted May 7, 2023 (edited) Hi there! I looked at the service manual that is on HiFI Engine and it also doesn't show the gas adjustments... I FOUND THIS THREAD... Read through it - it has the TP's listed Edited May 7, 2023 by itchitch 2
