CP554 Diode bridge compressor / Can’t get 3v in step 5 in setup
« on: April 05, 2024, 08:39:43 PM »
Hi JP,
I initially successfully passed step 5 with this unit, and everything worked until step 11… when pressing down the BYPASS switch to get 0.98VAC produced no change.
After much trying, I decided to try from the beginning.
Now I can’t get past step 5.
I am getting +16vDC and -16vDC no problem.
But I only see 0.064vDC across TP2 and TP3. TR2 takes a lot of turns, and it only changes a little.
I have reflowed all solder on PCB1 and checked orientation.
Thank you!
