> Just catching up on old mail... Thanks Joe At the bottom of the page here https://www.flickr.com/photos/97814409@N04/albums/72157671619263690 is what I built and am using / testing. Available current is more than twice what is expected to be needed and voltages are stable and non-interactive with others. Actual voltages are +/- 13.9, +/- 7.2, 12 and 5. The heatsink is only warmish at full load I kept two switcher step-downs, one for logic and one for peripherals such as sequencers and keyboards. Didn't have any LM337 for the -ve so jacked up a pair of LM79xx A couple of small post-photo changes were made to the board Joe ----- No virus found in this message.
