Not the ones sold in Europe or anywhere outside the USA. Don't know the brand of the Holland installed carbon comps in Hammond; they look just like AB's but are obviously different. The ones in Hammond organs & dynaco products post 1961 (the age of my PAS2 & ST70) are moisture resistant if the coating is not damaged. I don't know how the good ones were distinguished, but probably no moisture drift was one of those characteristics that salesmen could communicate orally but was a military secret in catalogs. Sprague also made an RCR07g# milspec resistor; I've seen it in catalogs but no telling where parts came from after they are installed.
Dynaco was installing wax encased GI paper caps in 1961, which had similar stability compared to the run of mill paper product. The mallory paper caps Hammond used drifted 40% off in 20 years. I've seen good things written about the parts used in HHScott products, also.

Dunno I replaced the Carbon Comps in My '63 Fender Bassman Guitar Amp.
Some drifted into close to double their nominal values.
Lotsa time/heat in a well enjoyed guitar amp.
No clue as to what 'brand' they might have been.
Most Fender amp owners discover the resultant sounds with n circuit spec Resistors is Markedly different from that of drifted resistors.
Some are horrified to hear what their amps sounded like on leaving the Factory.

There is no audio reason for using carbon composition in this day and age. It has 300 times the voltage coefficient of noise of metal film. In some high-voltage applications there is an electrical reason: surge capacity.
Unspoken issue (IMO) though is FM is a Poor medium both techincally and in content.
Reception issues.. the 15khz audio transmission ceiling... babbling on air 'personalities'.
Real life.

Maybe in Canada, but we have terrific FM programming on several stations here, including NPR
and listener sponsored stations. Would not be without it.
Great classical, jazz, blues, and folk, presented by highly knowledgeable people.
And a good FM tuner can sound excellent, especially on our local live FM broadcasts.

My hearing stops above 14 khz. I learn a lot of things about composers, the pieces, the era, the culture, from WUOL-FM announcers and at night the myclassical feed. You can try it on the internet - woul.org click play classical. I prefer the radio. my sound system is better in the music room than in the computer room. I'm using a Salvation Army resale shop radio with blown speaker drivers but working RCA jacks into a mixer, Peavey M-2600 amp, two SP2(2004) speakers high on poles. The computer+TV system is a Peavey MMA-875 monaural mixer amp to a 3 way resale shop speaker with 6" woofer that has boomy bass. My FM1 was retired for maintenance issues. but now the manual has become available from diyaudio.com

Contemporary broadcast audio chains are capable of delivering bit-perfect content right to the final over-the-air processor before the transmitter. Whether that results in excellence becomes fully in the hands of the programming team's tastes. Sounds like you're in a lucky market.
Our local station began in 1915 as 9XM, and has been in continuous operation since then,
next as WHA in 1922, and then adding WHA-FM in 1947. We now have 23 AM and FM stations
in our Wisconsin Public Radio network, which is closely associated with the University of Wisconsin.
The programming is uniformly excellent.
Our local, listener sponsored WORT-FM (since 1975) is also excellent, with a great diversity of programming
that is selected by local musicians and other local hosts. https://en.wikipedia.org/wiki/WORT

Nor are they high-voltage to an extent that would warrant carbon composition resistors.
False. The highest frequency in an FM tuner is 108+10.7=118.7MHz.
Whoa! electrons traveling only 118.7 mhz would certainly never resist turning in 2 mm circles for a hundred or so times through helical resistive path of a carbon film or metal film resistor! Substitute away, then put your failures in the closet for decennial admiration as a non-functional artifact.
118.7MHz is a frequency, not a speed. I have no idea what you re talking about, if anything.
FWIW, this summer I renovated a 1963 jukebox. I replace all the electrolytics in the preamp and power amp. I checked all the resistors, and had to replace about a third of them. The ones that I replaced were WAY out of spec while the ones I decided to leave in place were well within their OEM marked tolerance limits. My 1963 jukebox might have been built with a mixed inventory of pre and post moisture barrier treated resistors. Very interesting, thanks for posting that.
