I've got the power supply going. I have the correct rail voltages but no switching. I've tried feeding it a sinewave and replaced the ir2113s chip and still no switching.

Have you operated all pots and switches through their entire range to see if you could get signal to those ICs?
Typically, yes.
If you turn the pot to extremes, do you read 0 ohms between the center terminal and the respective outer terminals?

Are you saying that if you set the gain fully clockwise and you read only 1.5 ohms between the input and center pin that you still only have signal on the input terminal?
Ok so I have signal getting to u107 with the chip out but as soon as I put the chip in the signal is gone
The signal is probably being fed into the inverting input.
Are you sure that you don't have signal out of that IC?

With the ic out I have signal on pins 2 and 6. As soon as I put the ic in pin 2 turns into 55hz and pin 6 goes to around 130hz
What is the frequency of the test signal that you're driving into the amp?
Post the DC voltage on all terminals of U107 with the IC in the circuit. Copy and paste the following:
Pin 1:
Pin 2:
Pin 3:
Pin 4:
Pin 5:
Pin 6:
Pin 7:
Pin 8:

You previously stated that you were getting signal to the IC but you were driving 88Hz into the amp. That frequency won't change. The 55 and 130Hz are not from the input.
