I had a 46-350 with an electrolytic filter that corroded, burst, or fell apart with age and so couldn't be used even for display.  Apparently this is pretty common in these radios.

I couldn't find a replacement, so in desperation I decided to make my own.  Eventually I settled on PVC pipe that was almost the same O.D. as the original.  I cut it to length, capped one end with a circle of stiff plastic, and used some modelers putty and 600 grit sand paper to feather the glued edge, though it really didn't need it.

Then I sprayed it with aluminum paint from Ace hardware, several thin coats.  I took the mounting fixtures from the original cap by drilling rivets, then put them on my "aluminum" tube with small sheet metal screws.

My damaged original had colored wires coming out of the lower end, not lugs, so it was easy to put the new 'lytics inside my hand-made repro to save space inside the chassis.  I used a rubber washer a tiny bit larger than the I.D. of the PVC to hold the caps inside the tube.

At a glance my home-made filter cap looks very good.  The aluminum paint is a little darker than real aluminum, so it looks a little aged.





Thanks for the suggestion.  I may do something similar if I can't find a cap to use.

I have to get a closer look at it.
