Carbon comps and carbon films

Here are a couple of pictures showing the difference between the CC and Cf resistors.

Brian,

Cool pictures 8) I recognize the Iskra and Piher to the right and the carbon comp to the extreme left but does anyone know the origin/manufacturer of the two remaining carbon film resistors (skinny guy in the middle and to the left with rounded ends) ?

David,

I won't pretend to know all of these but the Iskra is on the far right, then a Piher and then I think the next one is a lower wattage piher, the far left CC is probably an AB. I don't know after that.

This picture came from Marc, maybe he knows.

might look at/for Beyschlag if anyone is looking for red carbon films that look about right (net searching, ebay, etc.). Also, I've seen Japanese carbon film having the red(or -ish) base color but haven't found any in the Marshall-correct values.

Revisiting this old post, I have seen these resistors in Klemt gear and in the R&S capacitor tester pictured but I still haven't confirmed who made them. Anyone?

They were supplied in cream card wrappers with plastic sleeve.

Hy-Stab is the name used but no makers mark or country of origin :(

(not that I'm an expert, but) my understanding of the "Hy-Stab" term (trademark??) is (was) a generic term for (then) new carbon film Rs (more stable then CComp--paint helps keep out moisture?). Someone older who has worked w/electronics in UK for a long time probably knows. Another possibility is an older version (bit diff. package) from some brand (the newer versions should generally be smaller I'd think). Wonder if somewhere out there there possibly exists a list of UK component makers (I've seen something like that for Japanese parts makers in a Japanese tech. mag.).

Neil,

Got any pictures of the resistors in the package? I was going off topic in the rewind thread so moved my inquiry to the proper place..

Dai,

Yeah that was the term for "Cracked carbon" resistors according to the catalog..
Do see them in a lot of electronics from Germany though hey could have been made anywhere.
