Hello everyone. I am a technician in electronics and I received for repair a preamp CJ that unfortunately has been repaired before by people not qualified for this. I could not identify the model but it has 9 double triodes and a 12x4 rectifier. Could someone please help me with the scheme?
I live in Brazil.

Could you post some pictures of the front, back, and inside. We can probably help identify it with some pictures. We have a lot of schematics in our database so once we identify the model, you can probably download the schematic to help you troubleshoot any problems.
