I'm assuming the farnell pots I linked won't fit this project?

Any other sources (that are not wildly expensive)?

they would fit the footprint, buuuut:
they are not high enough.
farnell offers other alps with a longer shaft, but alas, these are D-shaft, too. and D-shaft would not be cool with the LFO, since not all potentiometers are mounted with the same orientation...
BTW i built two modules with the alps (get them cheap here in germany , and with a full shaft), and they don't have enough tension IMHO. doesn't feel right to me.

the tempco's are to reduce drift due to temperature changes. this gets more important the longer the takes are you recording, and if you are interested in more precise tuning between the tracks.

Man I just noticed the prototype had an LFO switch and LED. I wish those had made it to the panel as well.

Is that just a switch changing capacitor values? How is the LED done? Not that I see room on the panels to fit anything on there. I was thinking of a wave folder to go between my two VCOS, maybe I could add an LED and LFO switch to that as a custom panel.

Did TH specifically ask you not expand his circuit in any way?
