    SA-7100 Ripple Current measurements-effects on protection board?

    Hi Everyone, I've been wrestling with a SA-7100 that has a horrid buzzing noise, for a couple of years now. I replaced electrolytics(including filter caps) and transistors using guides on this forum to no avail. Last night I used an android app to measure sound frequency, and found that when...

    Feeling a little buzzed :/

    Well, the receiver not me so much :) 2230 restored. Everything works great with a small itty bitty exception. The phono setting will give what sounds like a 60 cycle hum if the volume is up about 1/2 way. If I touch the chassis, it goes away. This started because in the loft where I had it, I...

    Marantz 2270 Crackling Noise

    A few months ago I picked up a cheap Marantz 2270 - it's the model my folks had when I was growing up so I'm very fond of it and it sounded better than I was expecting...but it's starting to show its age (and price). Main issue is a loud, persistent crackling noise from the right channel -...

    Sansui 5000x static

    I'm pretty sure I know what the usual suspects are here, but I figure it's better to ask than to assume, particularly with a group as knowledgeable as AK. I've got a Sansui 5000x that's been my daily driver for years. It's always had a fair amount of static on both channels on any input. The...

    Marantz 2226 hiss/static noise after few minutes.

    Hi guys, I have a problem with an old Marantz 2226. It made a hiss/static noise when I pushed the power on/off switch during few seconds every time, and the noise disappeared after approximately 6/7 seconds with no noise at all during hours. I though it needed a good cleaning with Deoxit...

    I recently bought a Hitachi KST-3400H AM/FM Radio and Tape Deck with the original two speakers. The Radio works well; clarity is fair as far as I can tell. When I play a cassette however, the right speaker makes a loud buzzing/humming sound and the level meter is pegged (maxed) for the right...

    Pulsing buzz varies speed with Volume/Bass. Any ideas?

    Kenwood KR-5600 receiver, just finished recapping Audio and Power Supply boards. After resetting bias it started making buzz/hum in a rhythmic pulse that would vary speed as either the Volume or Bass control was moved. Right channel only. Maybe some transistor oscillation? Haven't had one...

    Boo...(Hiss) on the inputs Lafayette LR-1500T

    Greetings all, I'm having a small issue with my LR-1500T receiver. I know that having some degree of noise is common in the phono stage, but that's not what this is. This is a broad-spectrum white noise that is probably 10 times what it should be. That said, if there is something hooked up to...

Along with that, a clicking noise would happen if you attempted to keep turning it below 98 and the needle would stay still. Upon opening up the...
