I've finished up a second Ukrainian Army BMP and I'm donating it to the Pedals for Ukraine relief effort.
This build follows exactly the same pattern as before using the Tayda board coupled with original KD521A diodes and KT3102E transistors (and sadly I'm out of NOS top hat KT3102E transistors, so future ones will have either reclaims or alternate form factor transistors... until those run out... because I'm not buying any from Russia at this point). The resistors are all modern Yageo and Speer 1% tolerance. The film capacitors are mostly Panasonic film capacitors with a few WIMA ones thrown in when I didn't have a Panasonic in that value.
The 3PDT daughter board is from Frog Pedals (just a newer model) and actuates the two LEDs - the red one for when it is in bypass mode, and the green one for active mode. Because these are older Russian / Soviet LEDs, they are dimmer than what most people are used to modernly - especially the green one! All of the connections to the jacks, as well as the wiring to the LEDs themselves is wrapped in tubular heat shrink to protect the solder joints.
The enclosure is a copy of the EHX-style enclosure that the Tayda boards are designed to go into. The potentiometers are all Alpha, and I'm using new production EHX knobs. The enclosure is hand decaled and painted in "Ukrainian" (definitely not Russian anymore) 4BO green with several coats of flat lacquer to give it a military appearance.
