looking for a replacement power supply for some vintage effects units - Yamaha Rev 7 / 5 and SPX (90 etc).
The original supplies can be recapped, but some units I have the supplies are actually missing!
The supply needs:
+/- 18V DC AND +5V DC output, with about 2A on the 5V DC output.
Have searched the internet, but can’t seem to find anything that matches this spec…
The original board is branded Yamaha LC 92750 circa 1980’s.Yamaha LC 92750
If anyone familiar with this type of supply or know maybe how to alter something available to fit the purpose I’d be very grateful.
