LO TENGO A UN MAGNIFICO

Submitted by jeanluc

I have been given a Sansui 7070 with a defective power section (caused by a short-circuit on the output). I have replaced numerous fuse-resistors and the power transistors (with equivalents, not original parts) but it still does not work! Any suggestions, previous experience, comments? As well, the service manual does not show the voltages at the test points (too dark). Do anybody have a better copy? Thanks!
PS: I have listened to this unit when it was still functioning and it was clearly an exceptional amplifier (for the time). I'd love to resuscitate it!
