To no one's great surprise, just replacing the two transistors did not fix the Cheapowatt.
Something went POP soon as I flipped on the 120vAC. Think it was a new Transistor, but no visual damage. No output voltage.
The cheapowatt, is Dead.
New Fairchild transistors felt heavier than the failed ones. Attributed it to the longer leads, but after removal with short legs, still felt heavier.
I used up the rest of my Solder wick, trying to pull some components clear of the circuit board without damage to either. Practice. I am not very good with it. Kind of frustrating getting the wick in the exact right spot when solder liquefies. I think the suction gun would be better, or stiffer solder wick.
Those Capacitors are pretty light in weight.
Anyway, not sure if I am going Megawatt or MeanWell. I'm going to research these hiccupp/current limiting modes, and perhaps send off an e mail to both companies. See if I get an answer different than what is published online already.
I really want to know the behavior of both in a true extended overload situation before dipping my big toe into the power supply pool again. I want a 30 amp plus manual bulk charger, an extended absorption charger, and a finish charger too.
One question I have to Mena, Niner and green, is can you read any numbers on the voltage trim pot? I'd assume They would be 1000 ohms like my cheapowatt but It's be nice to know for sure.
