Can anyone suggest the specs to look for and where I could possibly buy one. I had a 200mA one for testing, my PCB's for the original supply were rinted the wrong size so cant use them. Got all my modules working with the only problem being my power supply cannot handle all the modules at one time, pitch tracking etc is terrible as a result. Kris Bishop

I use switch mode PSU's, 2 seperate 15Vdc units, one for +15, one for -15. Derive 5Vdc with 7812 from the one used for +15V.(farnell: 2 times 494-9638 or similar)Farnell also has triple output PSU's (+15, -15, +5) for about 85 euro's...

I bought one from RS that has +15 and -15 v with 1.5 amps on each. It's tiny and only cost \ufffd40. works a treat and now my synth is up and running, all tuned and working with a digital interface which I can run from the PC or any of my other synths. Man it sounds good. One thing though I built the multi 12db filter and the results are rubbish, is this something wrong that I have done or is it the general result. No high squeeks from the high Q and low Cutoff. Calibrated several times Kris
