Hi All,

I was wondering if any of you know how the original DPDT was wired?  I am installing a 3PDT switch to add an LED.

Thanks

Hi All:

Wired up using ver 2.  Used a .47uf instead of a .390uf.  All caps are +25v rated.

Here's my issue:
Everything works, but it sounds really thin and there is a huge volume drop.

With that said, I have included some images and here are the voltages of the IC.
IC1 pin 3(+ input) is off, and IC3 pin 7(to + supply) is off.

Doesn't hum.  The pictures showf the .47uf cap almost touching the ic pins, but it doesn't when in place.

IC1
1 - 4.45v
2 - 4.46v
3 - 1.2v ****
4 - 0v
5 - 4.4v
6 - 4.4v
7 - 4.6v
8 - 9v

IC2
1 - 4.6v
2 - 4.6v
3 - 4.6v
4 - -8.7v
5 - 4.5v
6 - 4.6v
7 - 4.6v
8 - 16.9v

IC3
1 - 9.3v
2 - 4.5v
3 - 0
4 - -4.7v
5 - -9.1v
6 - 4.5v
7 - 0v  *****
8 - 9v









Please advise.

Thanks!
