[R-390] Power Supply Module caps

[Jim]

I did the capacitor "re-stuff" for the R-390A
What a PAIN!
Cut them open and clean out the gunk..
Drill and tap the aluminum..
find small brass screws and screw them in....
Tin, solder and install the new capacitors....
JB Weld the whole mess back together....
