There's a schematic now available here:
https://aionelectronics.com/schem/guyatone_ps-021.pngI want to draw a layout but I'm not 100% sure which components you'll need to eliminate to completely get rid of the flip flop switching system.
I was thinking: Q9, Q10, Q11, R15, R16, R20, R41, R69 and C10.
Any help would be appreciated.
