    Butchered Later Revision G-7700

    Working my way through a very butchered G-7700, it went to an absolute hack shop, to a reputable tech who unfortunately passed away before he could get to it, and now to me. So far it seems like one channel is probably ok to go but my other channel keeps smoking R51 and R53 with no outputs...

    F-2980...too hot transistors

    Hello everybody! I'm new here. I am the lucky owner of the Sansui G-7700. I have successfully restored the right channel: replaced the output transistors and 0.33 Ohm resistors. Adjusted the Bias Currents of the left and right channels: 3.3 mV, balancing at the outputs, respectively, +/- 6 mV...

    G-7700 Digital Display -not reading proper (FM) frequency

    Hi Everyone. I have scoured the internet, and these great forums on Audiokarma for some suggestions on the following problem... The 40pin display IC on the display PCB was replaced recently due to some of the display segments not working. The problem now is that the digital (vacuum fluorescent)...

    Re: Sansui G-7700 Dual Emitter Resistor

    I'm restoring a Sansui G-7700. One channel is gone. Burned-out parts include a .33-ohm 5W dual emitter resistor. Does anyone here in the USA sell these? Getting single emitter resistors from Mouser is no issue, but getting a dual (3-terminal) emitter resistor has got me stumped. Thanks for your...
