Cheers!

i sent out PMs/emails to all who ordered PCBs/panels. please check you PM's, i am missing the response of quite a few people.

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

Any other sources (that are not wildly expensive)?

btw. do I really have to use tempco's??

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.

Sorry for coming to this thread late. Are there any PCBs left? If so, I would like to order:

1x circuit PCB
1x eurorack PCB
1x front panel

Thanks,
jp1971

there are quite a few open orders, and i actually wanted to keep a few spares just in case something gets lost in the mail. but i will put you on the waiting list.

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?
