    Conrad Johnson MV100 blowing output tubes

    I'm helping a friend fix his Conrad Johnson MV100. He brought it to me last year with blown output tubes. I found the bad ones, replaced every tube that didn't test new, set the bias and off he went. It ran about a year, now he's back with more blown tubes. (left channel only) I thought I would...

    Peerless 16039 output transformer needed for Heathkit W-5M

    Someone on the DYI blog said he put one in the oven, on a moist cloth, set at 230 for two hours.. It became soft enough to ease it out of the case. He then froze it and chipped away at the tar to expose the bond points. What have I got to lose?

    Peerless 16039 output transformer needed for Heathkit W-5M

    Looks like rewinds are in the $200-$300 range. Ironic timing as the customer just called as I was looking it up. He asked me to put it aside so he can think on it, which translates to mean I'm unlikely get paid for work done. I think I'll try John suggestion, I have had some luck reattaching...

    Peerless 16039 output transformer needed for Heathkit W-5M

    I took a pair of these mono-blocks in for recapping/restoration. The good news is, I found out the incredible cult following these amplifiers have, which implies the customer is less likely balk at the bill. The bad news is after doing all the work of replacing the caps and resistors, one of the...

    Kyocera A710 w/high noise floor

    I have a Kyocera A710 integrated amp exhibiting random crunchy/rumbley noises, on both channels, all inputs, all outputs. The left side being slightly noisier than the right. This is important because it rules out the (single) power supply as being the root cause. The controls don't seem to...

    McIntosh MI-300

    McIntosh MI-300 mono-block power amplifiers. After reading all the replies I went on the hunt, I called the McIntosh factory, No engineer or technician from that era was still employed there from that time period, the early 1950's. They did have data on the MI-200, but not the MI-300. The MI...

    Must-Have Sansui Tuners other than TU-X1?

    I just bought a TU-9500 (1973 vintage) because it is the mate to my AU-9500 integrated amplifier. It is a fantastic tuner. I will likely recap it (power supply caps only) just because those caps are 40+ years old. My guess is the sound can only improve.

    MA6600 display fix.

    For those of you who bought the MA6600 when it first came out and had the display scroll off screen to the left on power-up: the problem was the E-Prom all along. The prom sits on the back of the display board. The factory should send it to you free of charge by just calling. Mine was long...

    Anything to gain using high powered amp with Cornwalls?

    So long as you are using a tube amp, the power lever is a mater of preference. I tried a high quality solid-state amp (McIntosh MA6600) the horns can't take the sharp transits. I switched to 50 watt tube amps (Luxman MB3045) and was much happier.

    McIntosh MI-300

    About 40 years ago I came across a pair of 300 watt industrial McIntosh mono-block amplifiers labeled MI-300. They were separate amp/power supply chassis. The most likely application would have been a large movie theater. Mine were lost in a fire, 1975...
