    First time Sansui receiver options

Currently there’s a 5000a, 771 and 7070 on gumtree all for around the AU$600-700 mark. There is a lovely...

    Sansui bias help

    Hey everyone. This is my first post here so apologies if in the wrong place. My issue is, and I have had this happen twice now, on a sansui 661 (or 771) the bias sits at 29 to 31 and doesn't move past that. If I turn the trim pot, it'll go up or down 1 mv. Same behavior both channels. The...

    No DC Bias in 8010

    Hi, I start serviced my "new" 8010 (Europe version of 771) and saw some minor (I hope) problems: noise from both channels on minimal volume position, variable DC voltage on output- 2-15 mV, and most strange thing - no DC Bias!!! On both channels its 0 and not changed during adjustment with...

    Sansui 771 10DC-1 10DC-1R

    I have just started renovating this 771 and saw this repair on the power circuit board. Someone has used a bridge rectifier to replace the 10DC-1R. I have noticed on here that most people replace these with a pair of normal diodes but I have sourced some from Silicon Ark. Should look more standard.

    Sansui 771?

    I know these are pretty well regarded here, though searching the forum finds wide opinions on how they compare to other Sansui receivers. I have a 9090, which I find very impressive, though I do not need that much power. Local guy who buys/repairs/sells has one. He even told me he picked it...

    Valuation for Sansui 771

    I have a Sansui 771, but it isn't flawless. The fuse type lamp for the signal display has been soldered to the clip. I don't have the tools or skills to fix it. Aside from that, two other lamps seem to have a loose connection - they work, but may require a tap to blaze to full glory. All...

    Finally fixed my 771

    I bought a 771 from a flea market last year and enjoyed it for a while. It started popping and cracking on the left channel, and near the same time I stumbled upon a Realistic STA-90 that work fine. So I swapped it in and set the 771 aside. I recapped the 771 ~6 months back, but a hiss...
