    Rotel RX-803 in protection after replacing Q605 & Q606

    This amp was coughing up occasional hairballs of noise/static. Noise was coming from the power amp, and this was after a full re-cap and replacement of some other questionable transistors. In an attempt to fix the noise, I replaced Q605 and Q606, which were 2SA912, with KSA1013. Now I'm stuck...

    (Slightly) Noisy and (Slightly) dull AU-666

    Hi Everyone. A while ago I used your collective expertise to help me choose my current amp, and I ended up with an AU-317 which has been an absolute joy since the day I brought it home. I know it is perhaps not the most sought-after Sansui but it was within my budget at the time and I love the...

    Rotel RX-803 - 2SA912 sub?

    I'm trying to eliminate the last few gremlins in this Rotel. It crackles a bit and I've read that KSA912 gets noisy (and hot) so I'd like to replace Q605 and Q606 on the main amp board, which are listed as "main amp bias compensator". KSA1013 seems to be the go-to sub, but I don't have any on...

    Sony C15ESD noisy mechanism

    So, the other day while at a thrift shop I finally happened upon a remote control for my Sony CDP-707esd. It was only $10, but it was taped to a CDP-C15ESD 10 disk cartridge changer. I hurried home and tried my new remote on the 707... and BOOM! ...it worked. So, now I have a clean C15 just...

    Volume pot cleaning guide for AU-717

    This week I was wrapping up an AU-717 overhaul and noticed the volume pot was noisy around the 9 o'clock region. My first attempt and fixing it was to turn off the amp and work the pot back and forth through the full range a couple dozen times. This didn't help so I knew I needed to do something...

    Why do records seem to age and wear so differently?

    It mystifies me that while a Columbia recording of Leonard Bernstein conducting "On the Waterfront" and "West Side Story" in like 1961 sounds terrific, despite being played hundreds of times in all kinds of unthinkable circumstances (possibly even on a child's Mickey Mouse record player!), Keith...

    JVC JA-S77 - Noise Issues

    I have a JVC JA-S77 integrated amp that sounds wonderful except for a few issues. When I have no music playing, I turn up the volume to see if there is any static or noise of any kind coming from any of the input channels. Dead silent on the Tuner and AUX channels, but Phono 1 is noisy and Phono...
