Title: Glam - no chorusing
Post by: sharpan.sv on April 09, 2016, 06:33:49 AM
Hello everyone! I've build glam chorus, but it isn't chorusing. It passes only clean signal at slightly lower volume. Controls doesn't change the sound but Lfo is working - D2 blinking and reacts to rate control. I presume that depth pot also working, but it's hard to tell. Voltages on opamp are good
but all the voltages on 2399 that should be around 2.5V are very low - around 0.25V (5V and ground are OK on pt2399). I've tried anothet 2399 - same result.
Does anybody knows what could be the reason for this?

Both pt2399 I've tried were dead. Now I've got new one and chorus is working.
