From the vendor
Based on the traced commercial schematic (rather than the vintage paper schematic which one could argue is more authentic, cool and certainly uses less parts...)
No affiliation here just fun for DIYers. Full Build document provided.
PCB colour might vary as per my whim. First run of v2 is Black!
Fits 125b enclosure with top mount jacks
IN STOCK - Jan 28th
