    Tips for restoring FM performance in vintage Marantz tuners

    I'm asking for your tips for restoring FM performance in vintage Marantz tuners/receivers. The receivers I see vary widely in their ability to pull in stations, even with the same model. The best ones perform well before any alignment or parts replacements are made, and very slightly better...

    Pioneer SX-680 no tuner - help!

    Hi All, I got this nice little receiver in a trade and everything works fine, but the tuner. No AM or FM.

    KT-7500 Power switch

    I have a KT-7500 and have had it sitting in my study for about 7 years. It was part of a deal to buy a Model 600. Now I've sold my Model 600 (not working) to an AK subscriber who is bringing it back to life. The replacement is a nice KA-7300 that will be delivered on Wednesday. My thought was to...

    Tuner dial spread

    I am working on an MCS 3230. Going through and adjusting the FM tuner section. It has the typical steps of setting the dial to a signal at the high end of the dial and adjusting a trimmer capacitor. Then tuning to a signal at the low end of the dial and adjusting a variable inductor. The problem...

    SX-434 FM issues

    Hey guys, so following a recap my SX-434s FM board seems out if wack. The tuning needle, when I'm FM mode appears to be working as if it were in the AM setting. The needle won't deflect past the center point. Then, if FM muting is turned on/off there is a pop. When muting is turned off I get...

    Fisher FM-100-B issues

    I've just picked up a Fisher FM-100-B tube tuner and it's a nice looking piece of equipment. I am pairing it with an X-100B integrated amplifier (and some Tekton Lore speakers). Cincinnati is lucky to have a good classical station, two stations which between them maybe equal ONE occasionally...

    Dear all, I bought this beautiful Yamaha T85 from a thrift store in unknown condition. I have just checked at home, I hooked up to an amplifier. It does turn on, the FM signal noise was heard, but unfortunately I could not tune in the channel. The reason was because only the left display could...

    SX-737 Tuner issue

    I picked up a nice SX-737 and want to change all the old caps and transistors before I give to my son. After I had a successful work with my other SX-828, we made a kind of sound-/tuner check between these two nice receivers. Bevor I started, we compered the Tuner of the 828 with the 737. My...

    I need to attempt minor repairs on my new KT-615 Tuner. Both bulbs are out and the stereo/mono switch won’t lock in the in position.

    CT-800 Lamp Modifications

    Hi all, I recently picked up a CT-800 for a whopping $30 in what I'd call fantastic condition. The lamps are out, which didn't surprise me for a 40+ year old model, and I've ordered replacements to bring the tuner back to life at night. Upon receiving I tore the unit down and did a deep clean...

    I have a Sansui TU-555 tuner, and the stereo lamp is not lighting up on stereo channels. I have examined the lamp, and I cannot tell if it is defective (it's very small). This may be a silly question, but how can I tell if I'm receiving the channel in stereo, since the lamp is not coming on...

    Riddle Me This Batman: NAD loses FM reception only when case is attached. SOLVED

    Edit: Solved, see post #7. Here's a real humdinger. Yesterday, I turned on my NAD 7155, tuned into a local FM station, and left it on in the background. I stepped outside for a second, and come back in, and all I hear is static. It wouldn't pick up any stations at all ... I hit the FM search...
