Pot working backwards?
« on: March 06, 2021, 08:24:04 AM »
Howdy Folks,
Built a ts808 from a schematic. The overdrive is an A500K pot, it works, but the overdrive decreases as the pot is turned clockwise. In the snip of the schematic it looks like pin 1 is open. I've tried a reverse pot and switching the wires but nothing doing... Suggestions anyone?
much thanks
phil

The gain pot should be hooked up b/w lugs 1 and 2 so the resistance increases as the pot is turned up. The schematic doesn't indicate orientation (a real pet peeve actually).
