I have put a lithium batt in across what was C88 and cut the diodes from the track - all seems OK. )My previous post I should have said there was 4 V across the c88).
Loaded the replacement patches from here http://www.geocities.com/SunsetStrip/St ... info2.html
It took quite a lot of trials the USB sound from my main PC wasnt suitable had to go to a PC with AC97 audio and even that required an external amplifier to work sufficiently to make all the display flash and not too much or it dropped out to "err" I think the patches are a rough recording from an old tape - just like loading software into a Sinclair Spectrum - but I'm thankful that the patches at least exist.
I'm not sure if I will make the external mods to it, probably just the 2 knobs mod will be enough, I marked all the presets (shouldnt touch VR1) and worked VR2, VR5 a bit to test the waters and got scalded - it probably depends which patch is used for testing this, must note to keep my amp turned down
So thanks for the help its got an otherwise junked Poly running as it should
