I’m having an issue with a strange fluttering noise, I isolated the two sides with the calibration mode and it’s happening on the high side, as it reaches its quietest point of the wave there’s a strange rapid fluttering for half a second. Any ideas?
The only voltage measurement that seems off is the led on the high side, instead of ~1.8 I’m getting ~3v
Just desoldered the jumpers, reset the trimmers, soldered again and made no difference. It’s like half the cycle has this really fast fluttering in the high end, similar to the other thread I’ve bumped with the ring mod like sounds. Clock noise?
Or if clock isn’t the right term, something similar
Tried running off a battery, no improvement
When I tweaked the high trim pot slightly it started making the noise on its own with no input signal – sounded like a cat purring
The rate/intensity of the fluttering can be changed with the multiply control, though it is always faster than the rate of the effect

The first bit sounds like there’s two speeds overlaid, it is set extremely slow and there’s a medium and extremely fast trem at the same time. Once it gets up to a medium speed the issue goes away
The rate led action seems smooth until the quietest part of the wave when it seems to judder at the same time as the strange noise
I just moved the spacing knob and the rate jumped significantly
To clarify I had it set slow and I turned the spacing knob anticlockwise and the speed suddenly jumped to a very high rate
