Modular Synth Panels

I just got a clean Polyfusion formant filter pcb. I need a UA739 or a subcircuit to replace it.

Hi Gino,
If that's the one from the 'bay then I nearly bid against you, but decided to let it go! I would love any scans of the boards that you could do... I once had a complete Polyfusion Modular with the AS1 and the expander unit too. It went off to Hans Zimmer to fuel his wall buidling! This was before the days when I had a scanner other than one of those push along ones and my 35mm camera had a fault so all I have is a pile of very feint slides :-(
Good luck on your 739 hunt!

All the best,

Ben

Gino,

I'm not sure where you are based, but I found a couple of UK based retailers that appear to have these chips in stock.

One is Nikko Electronics, here:

Nikko 

and one is Cricklewood Electronics, here:

Cricklewood 

The search on Cricklewood also throws up a few possible equivalents that may come in useful.

Regards

Mike
