Gentlemen and any Ladies,

I have a National NC300 that I will be restoring. At minimum replacing

the
electrolytic capacitors.


Glad you brought that up. I have a couple of antique radios I would like

to
restore. All of them need replacements for the big can multi-section caps
in the power supply. Where does one find replacements for these today?
I just got a brand new Allied Catalog (I didn't even know they were still
in business) but they have nothing even vaguely similar.

One of these radios is very valuable to me sentimentally as it was the

first
radio I ever repaired, when I was 9 years old. It is an old Philco and
listening to shortwave after repairing it is probably what got me

interested
in electronics and radio in the first place.

I like your sign.

Good ones are scarce. New old stock dries up. There are some twist-lock
still being made but hard to find in the combination you need. One way is
to fudge the values or make changes in the power supply to make use of what
is available. Some just leave the can in for show and put single section
replacements below the chassis. Fortunately newer caps can be made smaller.
Sometimes you can fit the smaller axial and pc mount styles into the
hollowed out original. Hot glue and perfboard can help. I have even heard
of people gluing or waxing the original around the new ones for show.
