    Will I have a problem running stacked Advents parallel with my Sansui 7070?

    I'd like to run stacked Advents, can my Sansui handle them wired parallel? I've been reading opinions that are all over the place and unsure. Some say wire them in series, others say the sound will suffer from that, they should be parallel. I'm not a tech and don't want to hurt my receiver, any...

    Sansui 7070

    I have this Sansui 7070 at home on a trial basis before a potential purchase. $550 asking price. I’ve already determined the stereo light is out or maybe the circuit is not turning it on. It does tune in stereo FM, so I think that is ok. Also, the power light is out. List of items the...

    Hello! I’ve just nearly finished building this board and it’s beautiful. Very grateful to Ben for providing the BOM along with the blank PCB on eBay.

    Sansui 7070 High Bias and DC Voltage

    So I've been working on a Sansui 7070 I just found in a barn. The relay didn't click when I got it so I replaced the fuse resistors on the driver board F2624. I then replaced four transistors that tested bad on the same board. I had no problems after this and it sounded pretty good. I set the DC...

    Tiny Cables Inside the Amp

    I was thinking of using some thicker speaker cables (up to 12 or 14 awg) to get better sound, but when I opened up my vintage receiver (Sansui 7070), what I saw were 4 very tiny cables feeding the speaker A and B terminals (top left corner). Would it be futile to use speakers cables that are...

    Hi, I just purchased my second Sansui. A 7070 which I am really enjoying. One quick questions for the experts: Everything sounds great after about a minute of warming up, but initially, after the protection relay kicks in, the sound is a little bit garbled. Is this normal? What could cause...

    Yamaha R-900, Sansui G 3500 and 7070 comparison

    Hi I hope I am not comparing apples and oranges. The reason I am comparing is cos of all three are available for reasonable prices with Yamaha the cheapest. Sansui's market rate are already high in general, regardless of its model. I am more inclined for Sansui 7070 which is available for about...
