Death By Audio Apocalypse - On-Hold

From the post
Original FSB thread and schematic available here.
Rotary Switch is 2P5T and they are not always numbered.
I've called the 2 poles A & C.
When the switch is on "A-1" position on the other side is on "C-1" position... and so on.
Original circuits' schematics use Ge diodes but the Apocalypse's one doesn't. Need to test.

Check before you build · 3 values the reader of this layout was not sure of
- 250p ceramic left of the 12K, upper left: printed clearly, unusual value
- 110R below D2: printed clearly, unusual value
- transistor types are printed outside the board edge as '5088' (four) and 'MPSA06' (one, top centre left of the 2K2); matched to the nearest transistor by position
