    Sony TA-N77ES Power Amplifier - Help with VU Meter

    I have a Sony TA-N77ES power amplifier purchased from the original owner a couple of years ago. I used it a few times and it worked and sounded great. A few months afterwards, one of the power/VU meter needles stopped moving. Long story short, I had a tech look at it and he subsequently sent it...

    I was working on a tc-k333esg (k950) and while disassembling the front panel I accidentally broke both push buttons because I pulled the plastic covers off while they were pressed in. This caused the retaining bracket on the blue plastic pieces to break which means that the buttons cannot be...

    Sony CDP-31 CD Player Repair Help

    Hello forum! I posted this on the Digital Sources subforum, but I figure I'd post it here as well. I'm trying to repair my mother's 1987 Sony CDP-31.

    Headphone adapter, for sure vintage

    I got this, before I even find the amp. Because NOS stuff is impossible to find. From the Sony hifi era, love the color and the attention to detail.

    Sony RX77ES calibration fun!

    Spent some time with my 1991-ish era Sony RX77ES cassette deck getting it calibrated over the weekend. The playback speed was coming in around 2930 hz with a 3000 Hz test tape, which was irritating. Cracked her open, added a few drops of oil in what mechanical spots I could access easily, and...

    Hi, I’ve inherited a Sony PS-4750 that’s been fine for a year or so but has now suddenly started pulsing in speed. I try to fine tune it on the pitch control but as I get close there’s an audible whir from the deck (not through an amp, no connection) then the deck speeds up. Just as it seems to...

    Sony portable D-50 and D-14 DACs

    Two in my collection: a red D-50 and a black D-14. Seem to be the same model, but different colors and model numbers. I don't think they were called "Discman" that early. What DACs did they use?
