Re: HEP-722 available equivalent
Way back in the dark ages, even before the onset of RTL technology, one had to build using discrete circuitry. Now there happened to be a product of FENDER which was assigned the name of SIDEMAN. It was a stand alone accompaniment accessory with its capability of producing tempos/ beats of drums, sn...

Re: capacitor or MOV?
. Ahhhhh yes, those two different types, and if you are not using them frequently, leaving you always wondering . . . . which is which ? . . . for that next time you run across one of them. Ye olde Safety Capacitors: Class X capacitors are used in “across-the-line” applications where their failure w...

Re: Weird SMPS problem
. Ken 1 . . . . . from Edd 1 . . . come in please . . . I found one dried electrolytic in the secondary circuit and replaced it. All other electrolytics were tested with a capacitance meter and tested good. Why is it that I think that you STILL have one or more electrolytics with high ESR, in that u...

. In accordance as to what drive configuration they were using, check to see that there are not pull up resistors used and that your drive is then outputted on pins on pins 8 and 11 instead of 9 and 10. That is, unless you have circuit path traced the drive lines to the PS SW FETS. 73's de Edd :grin...

In which case then, any current limiting would have solely been attributable to the '317's controlling circuitry...

GREEEEEEEAAAT circuit. . . . as Tony the Tiger would say. . . . Used it ever since the data sheet came out on it back in the 70-80's, and even using the IC forerunners of the LM 317's, before that time frame.. There is a better circuit using two '350's with the second one handling the current aspect...
