good idea to add line caps to model 52?
#1

I'm finishing up the electrical work on an original 1934 model 52.  The radio as designed had no caps on the AC input line; the power cord went directly to the transformer through the power switch.

I'm replacing the cord, and planning to add an inline fuse (84 year old transformer), and was wondering if it was a good idea to add line capacitors?   My first thought was to add one across the line to filter out incoming "hash" on the power. 

I see multiple threads where people have added a cap from each line to chassis, to eliminate (or reduce?) the need for a chassis ground connection?  The radio has spring clip terminals for antenna and ground.

Not that I want to do it, but would a 3 wire power cord accomplish the same thing?

What would you experts do here?

PS - any idea how to clean the volume control?  It looks pretty close to totally sealed?

Thanks!

dave
