D’Lay v3 with optional tap tempo?

[Anonymous]

Sometimes you just want to fiddle around. Sometimes you want the minimum number of pedals with the maximum settings. Sometimes you’re bored and just want ALL THE OPTIONS. Sometimes you might like overcomplicating things as a challenge. And sometimes your drummer is some kind of masochistic percussionmonster with a thing for polyrhythm.
So my tap tempo will be optional. And the build is clear about the labels on the switches, but not always what exactly the switches do.
Unless one switch functions as an on/off for the tap tempo board, I will be adding a switch. It appears I can use a 4PDT to swap from the D’Lay time knob to the tap tempo board (unless there’s a quicker way to solder those without interference) and using the last pole, the D’Lay’s R22 will be switched to the TT board on one throw, and through a wire connected with the normal R22 resistor on the other.

Unless I’m wildly off on that, a couple questions.
Which pad of R22 on the V3 board coincides with the left pad on the V2 layout? Top or bottom?

The tap tempo BOM calls for a BS170 transistor. I’m finding this a little difficult to source. Does its successor the BS170-D26z work as well? The differences being 500ma current (300ma on the BS170) and 40pF capacitance (60pF on the BS170).

S2, the PWM speed cycle: Just how it sweeps through for the effect?
S3, the temp scale switch. Which scales, and in which order? 1/8, 1/4, 1/2?
The double time switch is pretty obvious.

Anything else I’m having a stroke over?
