IC's in paia preamp

[sean k]

Howdy Chaps, I've been outta this stuff for a year and more but I'm getting back into it I suppose. I've refound the Paia preamp with phantom power because I've recently picked up an old Mini disk to record stuff outside... especially old steam engines (big ones!) and I'd like to build the preamp at Paia.

and I was wondering what IC3 is?
also I'd be running it on +12VDC and -12VDC (two small sealed lead acid batteries) and I notice that VCC comes off the top of the positive end of the first 470uf cap and will most probably be about 15VDC or so. Do you think I'd still get 39VDC for the phantom using 12VDC as the power source. I'd omit the diodes at the 12VAC input and take out the reg's and put 100ohm resistors to change from AC to DC.
Anything else I haven't thought of?

I think what you'd want is somehting like a CD4049 or 4069? something with 6 NOT gates in it
its basically set up there as a osciallator which then goes into a voltage multiplier network that ups it up to around 39V.
