Phase 90 problem

[snufkin]

hey guys

my diy phase 90 has a bit of a bug

it makes a kind of schshhhhh as it is part of the way through the cycle (not very technical i know)

without me taking readings (i cant at the mo im away from home) is this symptomatic of somthing obvious ?

thanks if any one can help

Mine did the same thing until I took the perhaps heavy-handed step of removing the feedback resistor. It's the 22k resistor that's highlighted in red on the Tonepad layout, between IC2 pin 6 and IC3 pin 7. It still thumps a little bit, but it's hardly perceptible when you're playing.

cool i hope this is the fix i need

thanks
