Two Pass F5 Mono Blocks

This is a dual mono build of diyaudio Pass F5 v2. My build is similar to the new v3 which has detailed instructions here. My power supply is oversized, each of my mono power supplies should suffice for a stereo build. My build includes additional circuitry for quick (= no noise) shut-down. The parts alone cost me about 600€. Each side weighs about 6.5kg. The amplifiers are fully working and ready to use (230V).

Hepos Pre-Amplifier

Tube pre-amp with 2x PCC88 tubes. Includes power supply boards for heating and the amp itself. The build is almost complete. Connect the boards and transformer, put everything into a casing, and you are ready to go.
