Hi Gents,
been working on a Sansui Seven receiver and the right channel crackles intermittently audio is fine just the intermittent pops that at times is loud to disengage the relay for a sec or two and then the relay engages once again ,i have tried swapping the driver boards around and the pop and crackle moves to the left channel ....... i have replaced the three electrolytics also the ceramic caps swapped transistors from the other channel driver board replaced diodes too checked resistance of resistors all ok but something still crackles and pops ......got me pulling my hair out this one will post photos of the boards
any help is very much appreciated
Regards
Roque
