Philco 623
#12

Hi All;
Terry, Thanks for the information..
I don't think these are real switchers, as they use regular transformers and LM723 for adjusting their outputs, thru some Hight power Transistors, they are smooth output, no ripple and hold current wise.. Of course I am way below their rating.. They are not an IBM style power supply, but used in Pre Ibm computers and in Lab experimental work.. I just looked under Power One, and what they have now is NOT the same as what I am using.. Their most current ones are true Switchers and mine are old Regulated Power Supplies..
THANK YOU Marty
