    Soundcraftsmen DX4200 surprise

    I recently bought a Soundcraftsmen DX4200 preamp equalizer to go through and sell. It was already an unusual unit, it does not have rack handles. First time I have seen that. I also noticed it felt heavy. Upon opening the top cover, I found a big attempt at reducing noise in the power supply...

    Mystery ADC Soundshaper 110 Variant - Similar to SS-100SL but different?

    Hi everyone! I recently picked up an ADC Sound Shaper 110 equalizer on Facebook Marketplace. It’s a 10-band stereo EQ with a built-in spectrum analyzer. To be honest, I’d never heard of ADC (Audio Dynamics Corporation) before. I mainly bought it for the aesthetics—it looks great in my setup...

    Was gifted a Technics SH-8010 EQ by a coworker. Plugged it in on the bench and had power, and the switches on the front seem to work fine, everything lit up like it should. Tested on the bench from my PC with a 3.5mm to RCA into a pioneer Sx-780 I've been working on and had a good output, but...

    MQ-101 Power Supply

    This post is a long shot, but here goes! Given that there was only little over 6,000 MQ-101 units made originally, it's over 45 years since they were last produced, probably only a small portion of the units that remain in use, and a very few being operated in European mains voltage areas...

    Painting the cover of the equalizer Fisher EQ-870

    Friends, I got a free Fisher EQ-870 equalizer, cheap of course, but pure Japanese. The lid was rusty, everything was fine inside, but according to the schematic, there was nothing good inside anyway. So, on one side the paint was swollen, and there the rust did its job. Anyway, I washed it, it...
