    Sansui 771 Clean-up

    I was gifted a 771 by a friend a couple of days ago. He said there were a couple of problems with it, sound cut-out when moving some of the pots maybe a couple of other issues. He had moved on to other equipment and was hoping it would find a good home. I told him I would be happy to take it...

    Sansui 771 - Right Channel Issue

    Hello all, Been a lurker for a while, but finally made an account in order to make a thread to hopefully figure something out. I brought home a 771 last week, and both channels worked fine, but we’re scratchy. I used some DeOxit on all the functions, and that cleared things right up. For the...

    Sansui 771: incorrect polarities for C17 / C18 on F-1504 preamp board and schematic ?

    Hi, I have been wondering what caused some low background noise on a 771 which I almost completely restored. Two electrolytics on the F-1504 preamp board (C17 and C18) apparently have incorrect polarities both on the schematic and the pcb silkscreen. They had -5V accross them. The 2SC1313 were...

    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...
