D*A*M: Buzzotron, Tag Board Layout

DAM Buzzotron trace b0224b7be8d0

The Buzzotron is almost identical to the original layout for the Buzzaround, which was also built on tag board.  It sounds pretty good – a bit low on output on some settings, but otherwise a very nice sounding MKIII variant.   The Buzzotron only has minor differences to the Buzzaround – bias resistors on the … Read more

In the very early days EH, component values varied quite a lot so this layout is based on Kitraes schematic HERE. There is also some notes and info the component values. Trannsistors is … Read more
