[TVARC] Need Some Parts For My “QJE-50A SMPS!”

[Tom G]

Hi, Folks!

My 50A Switching Supply gave up the ghost 👻 last year.  I finally got to repairing my “New” (out of warranty) supply and have discovered the issues.  As I noticed that each of the NPN Power Transistors had cracked and lifted lands due to stress caused by their Heat Sinks!

The two failed transistors took out two caps and two resistors.  They overheated and also went poof!

Long story short... I was wondering if anyone has these parts?

(2)  1.8 Ω, 1 Watt, Metal Film Resistors

(2)  1 pF, 1 kV Ceramic Disc Caps

(2)  2SC3714  (NPN)  Power Transistors  (TO-3PL Package)

(2)  40CPQ100  Schottky Rectifiers  (TO-247AD Package)

If you are able to help me out, please let me know!

TNX Folks!
