Circuit for Topward 3303D attatched.

janbo:
I have come to the conclusion this is the most keep secret Topward has. I have called sent emails to no avail so I have taken a picture of the board and mark the bad parts. Hoping someone has a board and can tell me the value and part numbers of the transistors and resistors.

Best Regards

Ron

Smoke Bandit:
Hi, I have one of these Topward PSU's with the master circuit amp control clamped down not allowing the current limit to work. The op amp has been changed so now think it is in the control circuit for the amp. As above, following the circuitry is proving to be a mission. Any chance you could share your redrawn circuit again please? I cannot access page two where it is posted. Thanks and regards
