    I'm having a very similar issue as this user had previously here - Sansui 9090 Fm Stereo stopped working, Fm Reception OK Doesn't look like he found a solution and I'm a bit unsure of where to start.

    Sansui 9090 - FM light stays on all the time

    Hello! I have a Sansui 9090, the issue is that the FM light stays on no matter what source is selected. I've tried cleaning the selector switch with contact cleaner to no avail. Short of removing the switch and cleaning it, is there anything else I should be looking at? TIA!!!

    Sansui 9090 no signal on left channel

    I have not used my Sansui 9090 for several months. I connected it today as stand alone and with a pre-amp but left channel doesn't have any signal or sound in Stereo mode. Speaker is good as the left channel works in "Mono" mode without the pre-amp. What could be the issue? Is this...

    Sansui 9090 Power Switch

    The power switch on my 9090 is going out. I have to push it numerous time before it will stick on. Same thing turning off. Usually, I can make it turn off by tugging slightly on the switch to "unclick". It seems like it something mechanical (as opposed to electrical). I saw this replacement on...

    Sansui 9090 or McIntosh MA6100 - what should I get?

    This will be my first vintage equipment buying experience. Do you guys have a preference one over other, and if so why? Both are approximately $1000 (sansui $100 less) with good sound and average cosmetic condition and unknown service history according to their current owners. I will be...

    Sansui 9090 F-2436 variable resistor replacements

    When I was working on the driver board, I replaced VR03 and 04 with Bournes 1k variable resistors 3362X-1-102LF since I had those on hand from my Eight restoration project. I'm in the process of putting together and order for Mouser, and thought I'd get the replacements for VR01 and 02, which...

    High resolution 9090 Service manual scan?

    The resolution of the scan of the service manual at HiFiEngine and the one in the AK database is not very good. When I printed it out, much of the small print was fuzzy. I can make most of it out with a magnifying glass, but just wondering if someone has a high resolution scan they can share?

    Sansui 9090 re-cap gone bad

    My Sansui 9090 (non DB) would not come out of protection mode, so I did some research on this site and from the help of past posts it wisely lead me to look at the F2436 driver circuit board. At location R30 I found a bad/open fusible resistor, so I replaced it along with 11 other resistors, 4...

    Sansui 9090: Original, everything works. Should I change anything?

    Just wondering what the prevailing thought on this is. Picked up a 9090 last week. Cleaned the inside. Volume/balance pots scratchy. Treated with Deoxit followed by Fader lube, and that completely cleared up. It has the modifications to the amp board, which likely were done at the factory...
