I have an RD2165 GD2 on the bench at the moment. I’ve just done a full recap (all electrolytics), and replaced the driver transistors, but I now cannot seem to get any bias current.
I’ve been over the work I’ve done and can’t see any errors. What would cause voltages to appear correct, but no cathode current on output tubes? Thoughts?
I’m very comfortable with tube electronics, but solid state stuff is still an area I’m learning.
