Build-up – Selector Power Supply
by Russ Knize on Feb.03, 2009, under
Power supplies for the selector and logic. Above are the +/-20VDC dual supplies intended for the analog multiplexers that were to be used in the selector/dubbing section. Below that is the 5V/1A supply for the control logic, display, etc. The 7805 is mounted on that little heatsink and I have a feeling it will overheat when the chassis cover is on. If it does, I’ll have to mount it to the chassis directly.
