    Harman Kardon 730 - Debugging Stereo Lamp

    Hi there! I am in the process of debugging/fixing what I believe is likely a dead stereo lamp in my HK-730. I placed the probes of my multimeter across the top two male probes shown in the attached photo - no continuity. Am I checking for contintuity at the right location? Before I replace the...

    HARMAN KARDON 330C - No Stereo Light or Sound?

    HK Experts! Very nice looking unit here, sounds excellent, very clean, quiet, FM alignment is fantastic but I'm only getting mono from the FM section - no light or stereo separation even with strong signal and antenna attached. Here's what I've done thus far: Controls cleaned and exercised...

    REALISTIC STA-78 No Stereo Light

    Squad, I've been on a little run of finding and replacing bad transistors this last week and brought three units back to life thanks to your help - a Concept 2.5, HK 330c, and most recently I've been working on an AA-6600 that's close to being done, so I thought I'd pull out a STA-78 I'd been...

    Sansui 9090DB

    Hi am new to this forum, so I really hope that I am posting in the correct place. I received this unit, owner says it wasn't playing in stereo, and had to "wiggle' the switch to get it to play sometimes (fixed that problem, with Deoxit). Well it played awesomely and sounded good. So as I was...

    SX-828 stereo light flicker in AUX, other modes

    Hello Pioneer friends. Have a Pioneer SX-828 back on the bench that I rebuilt about 3 years ago. It has a stereo indicator light that wants to slightly illuminate and flicker when playing music in modes other than FM. I'm pretty sure this isn't normal behavior (although my Marantz background...

    Sx-626 FM Stereo problem - Does this sound familiar? Need some help.

    Just finished recapping a lovely little SX-626, and the FM board doesn't want to go stereo. The Muting switch sometimes works, sometimes cancels all strong signals and goes silent. The Stereo light flickers while tuning, sometimes indicates stereo on weaker stations, but often does not glow on...

    Realistic STA-52B Problems (Stereo Indicator & FM Oscillator Trimmer)

    I'm having a few problems with my STA-52B I picked up for a garage stereo. I got the whole exterior reconditioned but the interior is giving me problems. The bulb for the stereo indicator didn't work, the manual says it's 6 V 60mA. So I wired in a 5mm red led with a 220 Ohm resistor on the...

    Pioneer SX-828 Please Help with the elusive Stereo Light

    EDIT: SOLVED! May have been the diode or the flying cap or both. When I got this, the STEREO bulb was constantly lit and very bright. Suspecting a transistor issue, I replaced Q19 (2SC968 with KSC2383) and Q20 (2SC711 with KSC1845) on the AF board. Thanks @markthefixer for your help...

    Stereo Light on a Sherwood S-7200

    Just picked up a nice one-owner Sherwood S-7200. Cleaned out the scratchy controls. Put in a new light or two. It operates beautifully and sounds great. Everything works on it, except for two things, of course, the power switch is bad, so there's a click-wheel switch in the power cord. Works...

    Sony Receiver Stereo Lamp Problem

    Everything works on this clean STR-6046A but for one problem: The FM Stereo lamp was not illuminating. Assumed it was a burned out bulb. It wasn't labeled, so to establish what lamp I'd need, I used my DMM, which read 6.9 volts DC - but I quickly found that wasn't only on an FM stereo signal...

    Marantz 2240B Stereo Light

    So this past weekend I went ahead and replaced all the factory lamps on my Marantz 2240B receiver with LEDs. I purchased an entire LED kit specifically for my model. The Stereo light never worked on it to begin with, and after taking out the original bulb, it was indeed, dead. Soldered all the...
