Hi

I managed to pick up an almost new ARC5 receiver a year ago and later
found a dynamotor. The set worked well for a bit then popped a smoothing
cap. My suggestion is to run on much lower HT (I have heard that these
sets might even work on 28v HT). I don't like modifying classic antique
sets such as these that are now getting harder to find - it immediately
reduces the value by over half apart from anything else, especially if
the front is altered as many were.

Tuning knobs can be found on internet auction sites, but even a short
piece of thin stiff plastic tubing slipped over the splines with some
solid rod inserted the other end and a knob will work.

There were many conversion articles/books written in the 1950s which
sometimes turn up at radio sales or auctions but these usually show
major mods to create a cheap and useful piece of ham radio gear. But
times have changed.

I just got an ARC 5 receiver and wonder if anyone has any tips on modifying
it; I had one in the 1960's, but can't remember what I had to do to it. I
think I replaced the dynamoter plug with a modern one, but dont remember how
I put the tuning knob on the front.
Also, what voltages are needed?
Thanks in advance for any info.
