Powersound Overdrive

[Chuck D. Bones]

C100 doesn't do anything in this circuit. Check out the TC1044 datasheet. The capacitor between pins 2 & 4 pumps charge to pin 5 when the TC1044 is used as voltage inverter. When it's used as a booster (like it is in the Powersound OD), pin 5 is left open and C100 can be omitted. Take a look at the Integral Preamp. The cap between pins 2 & 4 is omitted. There, I just saved everyone $0.25.

Yep. The charge pump was added as a block and this cap was never removed from the schematic. It won't hurt anything to install it, it's just not necessary.

It'll be removed from the board in the next PCB re-stock.
