Rebote Delay 2.5: FULL MODS THREAD

[Phend]

Re, Rebote 2.5 circuit Pin 15

Ok, I have looked for where "delay in" at pin 15 goes. Searched, but no luck, it was brought up here before. Found one answer on the net, "you can ignore that "delay in".
Any comment on this mystery ?

look up the datasheet for the PT2399, you will see that pins 16 and 15 form an opamp. pin 15 has an internal connection feeding the delay stack - kipper has his numbers wrong. see also the tonepad build docs.

It's kind-of useful to see the op-amps in the PT2399 separated out, but then you get this sort of problem where their outputs don't go anywhere. I wondered about this when I drew my own PT2399 symbol, but in the end I just detailed some of the internals inside a big rectangle and left it at that.
