Carbon composition resistors

[ChrisGibboGibson]

As a result of being a bit sad, and having not much better to do, I have just
totally renovated a vintage radio. As far as possible back to original
condition.

The one exception being a metal film 33K R stuck in there that now looks
totally out of place.

It should, of course, be carbon composition. Anyone got any?

Value? Wattage?

Value? Wattage?

I told you your newsreader was broke!

33k, it says so in the above post. As for wattage, I dunno, the normal size
ones!

I'd guess they'll be 0.25 watt (ish)

Tomorrow, I'll rummage the spares. They'll be though ceramic cased 1940's
style and not the 1930's and 1920's variety. Would they do?.

Just carve a little bakelite sleeve, and paint the color bands on it.
Seal up the ends with Plastic Wood. ;-)

For that matter, it might even look more authentic if you molded
a little body out of Plastic Wood, although you'd need to stain it.

Cheers!

Tried excavating any ancient landfill ?

Yes those would be fine. Thanks

I'm sure I either have one or can get one from a vintage radio
enthusiast friend of mine. If you get stuck, lemme know.

You might mention whether the other resistors have radial or axial leads. A
1/2W axial lead should be available anywhere, for less than the cost of
postage. An old radio I had, though, had radial lead resistors.

I've found a couple. Send me your address and I'll post 'em down.

A vintage Citroen fanatic friend tells me that this is actually done
with the old wax capacitors- no, condensers- in early car radios. Take
the end off, hollow out the foil inside, attach a small modern capacitor
to the leads, seal the end back on.

Thanks everyone for the offers.

I have some on the way.

A couple distributors still list carbon comp resistors in their
catalogs. For example, Allied and Digikey list
Ohmite OD (1/4 W), OF (1/2W), and OA (1W) series resistors at
fifty cents to two dollars each! That's right, not fifty cents
per hundred, but fifty cents each, and there's not much discount
for buying by the hundred.

These are almost certainly cylindrical brown parts, which may or may
not match the rest of the parts in your radio.

Might be best to give us a pic next time of the other Rs in there,
otherwise we dont know what period you want. 20s, 40s, 60s, all very
different.

I imagine it might also be poss to drill out the original fried R and
use it as a sleeve over a modern replacement. But the R body would be
very fragile I expect.
