I just got a Eico regulated power supply but without the schematic or any doc. The C- and the VAC all work fine, but the high voltage. Was cleaning in the basement a bit this afternoon, and stumbled across the schematic for this old Eico power supply on my work bench that’s.

Likewise, series diodes sum their voltage ratings, so the circuit is more robust anyway.For the price of a quality ultrafast diode from a reputable supplier — approx cents each for a Fairchild UF 1A, v — this protection is a bargain.

Thanks Rich - found that one on line - appears to be quite different - 1032 looks to have solid state bridge rectifier structure - could be the one I have was modified as the xfmer is disconnected for some reason - just starting to research it - I might have to draw my own schematic to see what was done in it before me - not sure if original owner was trying to modify it or troubleshoot it or what - mainly want to find out what it is supposed to be - rather surprised there is not a schematic on line somewhere - must not have been a very popular supplyGriz. Well - finally found a copy of the manual thanks to real nice guy on e-bay - so in the manual the voltage on the positive terminal of C2 is stated to be +42 v - based on that I am not sure what I need for a transformer as I am not able to locate the Eico part listed above - What does the AC output voltage of the xfmer need to be to provide the 42 volts - 42-0-42 or does it need to be higher? Thanks in advance for your inputs -It had better not exceed 50 volts peak, as the filter capacitors are only rated for 50 volts. So the maximum RMS output voltage would be 50/sqrt(2), or about 50. 0.707 = 35.35 volts. You need some margin, say 15% to cover line voltage and load variation, so I'd use nothing larger than a 30-0-30 VAC transformer.

Peak voltage on C2 for such a transformer would be 30. sqrt(2) or 30.

1.414 = 42.42 volts. Assuming the voltage specified in the manual is the no-load voltage, that checks.So: a 60 volt center tapped transformer (30-0-30 VAC).Steve Byan.
