I made an electronic card copied from the original card since the manufacturer of the equipment
no longer exist. Transitor and diode Parts are germanium type but still I am able to get these from
China. When I tested the the 3 fabricated cards will not regulate properly. The 2 cards will cause
overvoltage while the other 1 card will cause undervoltage. I would like to seek assistance
wht these cards wont regulate properly.
Attached is the schematic diagram of the card I made.View attachment 60687
