Dino's Flanger has a 120pf and 10pf ceramic caps in parallel for the timing cap. A board shot of a different unit shows one timing cap and empty holes where another would go. The original factory schematic depicts only a 120pf.
I believe this means that the actual capacitance for the timing cap would be chosen when the flanger was calibrated.

I'd say this is highly likely. My experience with 4046 high frequency clocks suggests that the variation from one chip to another is huge. Variation between different manufacturer's versions is even worse.

Does someone have a schematic for this flanger?

Links/pics are dead and I'm very interested how Mu-tron has done it. :icon_frown:

Thanks a lot!

I've reupped the schematic and many pictures to here;

Exciting, thank you very much!

There aren't many DIY projects with compressor and expander out there..
Thanks for help!

Is that Larry's project? I've been keeping an eye out for a morely pedal to house it. Thank you for sharing this I haven't seen it in a couple of years.

If you need anything for the project, let me know. I have a few Morley chassis, etched PCBs (empty and partially populated), and parts for this project kicking around.
