Thanks. I needed a link cable on the send return. Also I replaced c12 with electrolytic 2.2uf 35v tested and noise gone. I have replaced the mains switch and added filter on transformer primary. Changed op amps previously using the same chips new and installed holders. Added earth to centre tap...
Hi, good read thanks. I think I have the same noise. my amp is the 5212 1986. I am going to change TR1 I think it might be in that location. You said a capacitor change for the tatalum. What value cap did you you use please?
Thanks
