Psybok · 22nd April 2011, 03:01 PM

Hello, I am a french engineer, I have a problem on an amp SRX3801. The vitreous resistors R99B, R98B, R43B, R44B overheat and melt me C32B. Yet the amp works. Does anyone have a track he has give me to repair. Excuse my English :-) google. If someone speak french will be easier. Thank you in advance.
Bonjour, je suis un technicien francais, j'ai un probleme sur un ampli SRX3801. Les resistances vitrifié R99B, R98B, R43B, R44B surchauffe et me font fondre C32B. Pourtant l'ampli fonctionne. Quelqu'un a t il une piste a me donner pour la reparation. Excuser mon anglais google :-). Si quelqu'un parle le francais se sera plus simple. Merci d'avance.

Thank you but I already Schemes. I do not see what can cause this overheating.
Merci mais j'ai déjà les schémas. Je ne voit pas ce qui peut provoquer cette surchauffe.

Hi, I also have this exact same problem with the SRX 3801 - did you manage to diagnose the fault? Thanks, Jim
