Roland TR-505 stuff

Points for individual outs (audio signals-add ground from ground point)


Ground

Points for bit-crushing effects: just solder to leads and strike them against the other at pleasure.. i dont like bending stuff, but this is the way it came when i bought it second hand..

I bought a ROM expansion that adda DMX, LINN DRUM and LN1 sound samples.

Desolder IC11


Solder the ic socket


Solder the switch to the pcb



All done!

Selmer Buzz-Tone

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..


Expensive nos carbon comp build for a groupie:
They all sound 👍🏿.
