Synchro-bias
New ClassA
Finally what seems like a lifetime ( a bit dramatic but has been a few months) the V9 is complete, and due for a once over again to make sure there is no shorts. All new fresh capacitors -long life high temp FR PWs SU bipolars plus film output for phono.
Thyristors have continuity with heatsink yet when they were out on the heatsink there was no continuty
When the service manual states to turn before adjustment - VR301 VR302 and VR601 to be turned counter clockwise direction - ? this mean completely?
Step1 - done this before wire to ground and TP703 while doing adjustments for VR701/2
turn off V9
then
Step2
Connect 8 ohm load to speaker terminal ? does that mean 8ohm resistor or speaker, i have an 8ohm cheap pair of speakers - woofer has no capacitors yet is 8 ohm
Connect DMM to Q327 and TP502 - that does go to ground so negative on Q327 and positive on TP502?
turn off V9
then
Step3
with the ICQ mention wherev to put the probes so is fine
Sankens look a bit bent? not sure i might redo them?
