Astron VS-50M repair thread
« on: June 18, 2014, 04:55:08 PM »
I will be posting the repair of a astron supply I picked up. ATM it has a blown SCR and the meter pegs when powered up. So either a series pass ot LM723 bad.
While checking the transistors they all read about the same.

Also noticed no thermal grease on transistors
