I have been building Selmer Buzz Tones for a few groupies n fans recently.
Featuring original, near-impossible to source transistors, 2N2613 on choc brown paxoline board, on eyelets just like the original.
One small mod is the cap tuck away under the board, to give it some juice (otherwise it wont buzz!).
Cheapo build for a friend:
Another build.. featuring the Palenque astronaut..
