Hi!
I have this pedal with an issue of dropping voltage. Is has multiple voltages inside, 3v, 9, 27 volts. 2 boards interconnected. When I separate the boards, lower one with powersupply holds voltage ok leds on bottom board are working.
When I connect upper board, voltage drops in 1-2 sec and pedal turns off so I think issue is in the top board with FV - 1 chips.
I check every cap is tests ok with LCR meter, no shorted resistors. Nothing get's hot on IR camera. FV-1 chips heat up equally.
I have a minor delay effect when pedal is on untill it shuts off.
Here are the guts
Any ideas?
Any input is appreciated
