    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...

    Soundcraftsmen A5002 driver boards

    I have had a few amps with burned or damaged driver boards, so I decided to make some new ones. I also plan to make output boards to retrofit everything in the MA5002 wire-wrap rats-nest. The first version is basically a remake of the originals, with component and trace placement in the same...

    Soundcraftsmen EQ slider replacement

    After removing, disassembling, cleaning, lubing, reassembly, and soldering thousands of Soundcraftsmen sliders; I thought it would be nice to install some new ones. For the right price, it may balance out by saving all those hours on labor. There are currently no adapter boards for this purpose...

    Opinions sought: Soundcraftsmen DX4000 restoration

    Specifically, I am repairing/restoring a DX4000 and most of the pushbutton caps are either missing or cracked. I designed and 3D printed replacements for all 15 using TPU filament.

    Soundcraftsmen MTX S800 battery charger

    I needed a battery charger for a 144V hybrid tractor project I'm working on. I also have a MTX Soundcraftsmen S800 amp for parts. It is the same style as the old Soundcraftsmen PCR800, PM840/860 with regulated power supply. I needed the amp section to repair an S860, so I had everything else...

    Some wiring confusion that needs rectifying

    I bought a rare soundscraftsmen tube receiver. Recapped it and it’s working great. The part that confuses me is the rectifying circuit. One leg of the transformer goes to 2 opposite diodes producing a dc output. The other goes through a 150mf capacitor to ground. The transformer puts out 120v ac...

    Soundcraftsmen PM860 / PCR800 power-amp restoration

    I bought this amp in rough shape as a project to match my other PM860 beater amp. I should have taken before pictures. The inside was coated in heavy dust that was also oily. And all of the black sheet metal parts had the paint pealing off. I opted to fully disassemble the amp. Ultrasonic...

    Soundcraftsmen input board

    I designed an input board for the Soundcraftsmen PCR800, PM840/860, and similar amps. It will also work on the A5002 or most amps in general with the correct power source. It uses the built in +/- 15V supply in the PCR style amps. It provides a buffer for the input to the amp and will accept...

    Help with DC offset and Bias on amp. Soundcraftsmen circuit?

    I have a power amp made in Australia that i believe was used as an install amp in Cinemas. It's made by Auditec or AVE. It sounds kind of good, but on checking DC its showing around 350mA. There are 2 1k adjustment pots which i assumed were for DC and Bias but they're wound fully anticlockwise...

    Soundcraftsmen Vari-Portional Audio Buffer

    Just had a Soundcraftsmen RA7502 amp restored with new output transistors. A week into listening to it the "vari-portional audio buffer" light turned on. I understand the purpose of this feature but it's only lighting up on the left channel. Any explanation would be appreciated.

    Meters In The House! Soundcraftsmen MA 5002

    I recently picked up this Soundcraftsmen MA 5002. It's built like a Tank, and has taken my system to levels of detail I've seemed to be just shy of. It replaced a Soundcraftsmen S860 Mosfet. The 5002 has no Mosfets, but I'm really liking the warmth, and clarity it puts out. I've recently...
