I got a 7070. No sound. Protection relay doesnt click on replaced a few resistors and questionable caps now clicks on and off in a second. Still no sound or keping relay on. What am i missing. Ive heard of several resistors that are fused. Dont know wich ones and values.

I remember back in 1976 a friend of mine and I were looking in Hi Fidelity magazine and he saw the Sansui 7070 and loved it so much that he purchased one the next week. I could not afford one at that time. Fast forward to 2009 I found a one owner on Craigslist for 75.00 for the 7070 and Sansui FR 5080 turntable. I love it ! Running it through Cerwin Vega VS 120's.

I've this unit now for almost 25 years. It originally came with a pear of Sony Bowers & Wilkins SS-1005 speakers, which were thumpy. The unit now gives all its best through a pair of Wharfedale Diamond 10.1, which to my taste is a perfect match ... it's a wonderful machine !

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!
