Sola Sound Zonk II
Based on the Sola Sound Zonk II
From the post
Since I posted layouts for the Hornby Skewes Zonk Machine, version 1 and 2, Will Kenworthy posted links to 2 other schematics that were traced and posted over at the DAM forum for a version of the Zonk II under the Sola Sound name back in the 60's. I figured why not make layouts for them as well.
Version 1
Version 2
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
