relay attenuator development of my compatriot Maxim Volobuev. Assembled on takamisawa bistable relays. The case, pcb, are developed by me comprehensively, transformers are wound to order.
There are three versions of cases and layouts, 65 mm, 130 mm and 160 mm high. 160mm version for 2x200W amplifier or computer.

Looks like an extensive build. Good work.Hiraga 2x15+2x50watt

Great looking build.
How are the power transistors clamped to the heatsink?
on the reverse side of the board are capacitances, between them is a hole in the board through which the transistor is screwed to the radiator

I don’t press the board, there are 7mm holes in it, 6mm screw caps
Oh ok. I use the board.
Hello, I want to share my build of the honeybadger amp. After building and testing the boards it was time to build a nice case to hold the amps. I decided on a design that is very much inspired by Cambridge Audio. So after a lot of sawing, bending and sanding I am happy to share the result of the build.
It looks so good....Congrats...
In the end did you measured on dummy load the power RMS?
Thanks! I did measure up to 150 watt in 4 Ohm before the dummyresistor began to smoke. For me that is more than enough. DC voltage is +/- 55 Volts. It has been setup for 4 ohm. There are badgers running much higher DC voltages for 8 Ohm.
