    Marantz 2275 Left Channel very low

    This is the challenge I'm facing today with my 2275. I have a very low volume on the left channel (compared to right) both on speakers and headphones. However (surprisingly) this applies only on FM Stereo (mono doesn't work if we select the left channel but does if we select the right one). This...

    Project/One Mark IVB - Deviton 4080 FM mute and stereo problem

    Hi guys, I've encountered an odd problem with this Deviton 4080 receiver I've pickup up. First of all, it's an obscure German rebranding of an already obscure Project/One mark IVB receiver. (It says Mark IVB on the transformer and meters.) So I haven't been able to find any schematics or...

    Marantz 2215 - Lost left channel in FM stereo after re-cap

    I've been refurbishing a Marantz 2215 and just re-capped the MPX stereo decoding board (P400). Before recapping this board, everything worked fine. After re-capping, I no longer get output in the left channel in FM stereo mode. I get output in both channels when in mono mode. In aux mode I...

    Fisher 500T FM MPX Issues

    working on a 500T with issues in the MPX section (well, actually its a 440T with the guts of a 500T). I have never seen anything like the issue it's having so I am looking for suggestions. Basically, I am able to hear what I think is the 19KHz Tone, the L channel comes through clear with the...

    2285B - FM stereo works, but the stereo light doesn't come on

    Just doing a check of the 2285B before I send it back to my friend, and I finally plugged in an antenna to see if FM Stereo is working. Well, it does, but the FM Stereo light does not come on. And yes, the light works, because it works in all other modes (tape/aux/phono etc.). Not sure where...

    Pioneer sx 3600 fm stereo indicator not working

    I picked up this little pioneer at a garage sale. It needed some new bulbs and a cleanup, and I went ahead and recapped it. The fm stereo indicator didn't work when I got it, and still doesn't work even after the recap. The bulb isn't dead, though. The posts feeding the bulb are obviously not...

    Pioneer sx 3600 with no stereo indicator

    I got this little 3600 at a garage sale and figured it would be a good little unit for MY garage when I'm working on the car or my bikes. Anyway, I cleaned it up, recapped it, and replaced the couple known noisy transistors (2SA 826s-->2SA992 and 2SA798 --> 2x 2SA992s), replaced a couple bulbs...

    Hello I was hoping for some guidance on an issue I’m having with my 9090. First some quick back ground. When I purchased the unit it was working with the exception of the Indicator lights for FM and Phono. I can’t recall if the FM Stereo work at that time or not. I decided to recap and clean...

    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...
