Re: [ARSCLIST] Stereo records.

yeah, I'm not a big believer in "tube rolling", but that's a whole other topic. I have pretty good ears and I hear very little differences between tubes except when one is bad (tests bad) and one is good, or one is microphonic and one isn't. But then I don't like tube amps that "warm" (ie add a noticeable amount of harmonic distortion) the sound. I like accurate amps. Some are tube, some are solid-state. Depends on the input device and the speakers.

One of my more "audiophillic" friends was trying to prove to me how much difference there was in tubes using his "line stage" (ie distortion-adder since the clean way to switch between line-level sources is, well, a passive switch). All I could hear was how hummy his system was. But he's my friend and he paid lots and lots of cash for that thing so I just nodded my head and said, uh huh.

Yes, where would I have come up with this? We all stand on other's shoulders. But even if I didn't read VTV and other fine publications, the observant tube collector can spot a Euro tube in American clothing. The worst is opening up a new eBay purchase to realize you just paid $40 for a counterfeit Telefunken, a Russian tube that can be had for $4.

There was an article about this in the late Vacuum Tube Valley magazine. Eric Barbour, who used to contribute to them often, is quite well-informed on both ye olde dayes and modern tube production details.

RCA, even after it bought Victor, sourced many of its tubes from other
vendors. You'll see tubes made in Holland and Germany, rebranded RCA. It
came down to who had which tube type up and running on their lines. They
didn't like switching over production from one type to another. And from
what I understand of tube manufacturing, most all tube manufacturers in the
USA bought their tube parts from Sylvania, especially cathode assemblies and
grid wire. The manufacturing of the individual parts required much greater
attention to detail than the assembly of the tubes.

You know what? I completely forgot about that. Did they include
radios? Or was that left for a third party installation?


RCA provided the radios to Victor to install in the
machines; but before RCA bought Victor, RCA didn't have
much of any manufacturing capability to speak of. Most
RCA-badged equipment was acutally manufactured by GE or
Westinghouse and marketed be RCA.

Ironically, much like with the licensing arrangement with
Thompson today.
