Strange Voltages

[monokinetic]

Hi all,

I would like to ask if someone could open their MBFM to take some test measurements for me? You can find background information here:

Basically my board is behaving really strangely and it would help a lot to know what voltage I should expect to measure on the following pins:

IC3 OP3 and OP4

IC5 OP3 and OP4

These pins are on the right hand side of the TL074, at the top and bottom.

Anyone?

TIA
