Capt. Happy Posted May 5, 2022 Report Share Posted May 5, 2022 I have a 100V SRM 323A that I am trying to rewire for 120V. I haven't been able to find a diagram for the transformer, so I was hoping that someone could help me figure out how to rewire it. Right now the yellow, white, and grey wires are connected to one side of the plug and the brown and green wires are connected to the other. The blue and orange wires have been cut off, but I should be able to reconnect them with some careful soldering. Quote Link to comment Share on other sites More sharing options...
spritzer Posted May 5, 2022 Report Share Posted May 5, 2022 You need to replace those wires or it will never work and make sure they are connected into the transformer. You can lift up that plastic cover on the transformer to access the tie pins. Then bridge the following contacts on the PCB for 120V: 2,4,6 Quote Link to comment Share on other sites More sharing options...
Capt. Happy Posted May 7, 2022 Author Report Share Posted May 7, 2022 What are the output voltages on the transformer supposed to read? Stax coated the transformer cover with glue and I broke the leads from the transformer going to the tie pins while opening it. I was able to repair them and I'm about 90% sure they're in the right spots, but I want to be able to validate the output voltages from the transformer so I don't break the amp when I plug it in.

Capt. Happy Posted May 24, 2022 Author Report Share Posted May 24, 2022 I found this thread on Head-fi, and I was able to verify that my transformer secondaries were reading the correct voltages. I tested it and it's working great! Quote Link to comment Share on other sites More sharing options...
