Tech Help - Etcher's Paradise / Re: Ankh (Troubleshooting)
January 25, 2018, 04:30:05 PM
please see my other post, in my opinion there is a mistake in the schematic (47nF capacitor missing) which cause bad voltages on Q2 :

Tech Help - Etcher's Paradise / ANKH schematic mistake ?
January 25, 2018, 04:24:34 PM
Dear all,
i've seen the schematic posted on freestompboxes and i noticed that on ANKH is missing a capacitor (C4 on fsb schematic with value 47nf) which connect lug 2 of Gain pot to Q2 Gate.
Fortunately it correspond on ANKH board on the longest wire bridge , so just replacing the wire with a 47nF capacitor the ANKH became identical to fsb schematic.
I noticed also that on some breadboard circuit found on internet the same capacitor 47nF is used at the same time so i supposed is necessary and if omitted could compromise Q2 polarization.
See in attachment freestompboxes schematic.
