I wish I could find carbon comps (decent values) for two cents
each! Those days are long gone around these parts.

looks like a lot of Carbon Film ones are in the 3 cents each price
range to me..... those are 100 lot prices.... so its 3 buks a 100

They are a Dime Each if you wanna onze twoze them ..... so then its
3 buks for 30 of them......

I have the following pkgs of resistors, sealed, all allen bradley: 50 per
pack, 5%, $5 per bag

330 ohms, jan rcro7g331js 5 bags $5 per bag
1000 ohms RC07GF102J 3 bags
2200 ohms, JAN RCR07G222JS 3 bags

bag with about 25 new resisors of various types, some precision (1%), some
carbon up to 1 watt $3

bag of metal film resistors, mostly 1%, some may be better than that, $3

shipping will be no more than $4 now matter what you get, could be less

Hi, looking for some misc carbon comp resistors in 1/2watt size. Like to
find misc values (e.g. 1meg, 220k, whatever) to keep for my
amp/boatanchor projects. if you have any extras laying around whether 20
or 100 or whatever qty let me know at . thanks, dave,
n5wnm, okla city, ok

What kind of package? Are they similar to the Allen Bradley
cylinder packaging? Or, do they have a more "modern" look to
them? I generally look for the NOS Allen Bradley resistors when
I can find them.

Pete



No Pete... they are the newer packaging style... re carbon resistors
see comments from the other Bill Turner W6WRT regarding them.... I agree
with him.... long term they aren't as stable as the newer metal film
resistors

How stable do they need to be in an old radio where components values
can vary, sometimes by quite a bit, and the radio will still perform
just fine?

That depends partly on the circuit design and partly on how much any
other components in that circuit may have drifted. Without that
information, the question can not be answered.

The question is pretty much answered by the fact that most antique
radios used 20% carbon resistors. Many of these original resistors
have aged upwards of 100% over time, and the radios often still
run "just fine". The manufacturers saw no need to use high tolorence
components, and most of the circuits are self biasing and self
compensating to some degree.

Vintage radios aren't rocket science. Good NOS carbon
comps from reputable manufacturers are fine.

Well lets see how this plays.... I have to take this old solder joint
apart anyway to removed to leads from the capacitor.... or rubber insulated
wire... and in this same hole is this old resistor thats 19% off value..
Now this new resistor is going to cost me a whole 3 cents.... or even
if the thing was a dime ... now this new part doesn't look quite
like the old one.... it doesn't look like a dogbone... and it doesn't
even look like a AB Striped Resistor.... but its UNDER THE CHASSIS ..
and for 99% of the old radios that we restore... whats UNDER THE
CHASSIS is acceptable as long as it is good electrical practice
and makes the radio play like it is supposed to play....

Now if I am doing up a $10,000 Zenith Strat .... or a $75,000 Sparton
Nocturne.... then I'll make those new parts UNDER THE CHASSIS ....
look exactly like the old ones.... most any radio other than those high
end ones.... or if a customer want to pay me enough money I'll do it
on an AA5 plastic 1950's kitchen clock radio.... So where is the beef
about using a new part that is a whole lot closer to tolerance.. and
will stay there.... and the cost of the part is so cheap that it just
doesn't make sense to me to leave that 19% off resistor ...

I bet that you don't replace those little dog turd looking capacitors
that RCA used in the front ends of their radios either.... little black
sort of pointed on each end... like the 811K and 19K and a bunch of
these things...... now for a whole 15 to 25 cents each I can have
these nice looking new.. 1% tolerance silver mica caps .. and when I do
the alignment on that radio.. it will play like it is supposed to..
and stay that way for a lot of years...
