Re: SED Winged C St. Petersburg Stopped Making Receiving Tubes
That does suck that the best production tubes are no longer in production but we must be used to that by now, right? Seems like thats been the case since the mid 70's when I started looking for tubes for my stuff. My Dad always had mismatched brand el34's in his Eico Hf 89 audio power amp, but I suspect he just would buy whatever random el34 was in the bottom of the tube tester at the drugstore when one redplated to death. In the manual for that amp it stated that the Mullard el34's (they were budget tubes) plates would glow dull red in normal operation at the recommended 54ma @ 500 volts!!!
I rebuilt it 2 yrs ago and it runs at 45 ma at even higher plate voltage using the old eh el34's from the 90's that I had in my Matchless SC120 for my gigging years. They will not die. The matchless amp runs 540 volts at 50 ma with no redplating with those same tubes. Maybe I got the magic quad of those tubes or something, I know every one else hates them. They sound fine to me and still put out rated power.
There are gobs of nos tv sweep tubes out there, they can't all sound like crap in a properly designed circuit. I keep buying tube caddies full of them offa ebay:)
If you have not read it, you should read "The Right Stuff" by Tom Wolfe. The humor and irony don't come through in the movie adaptation. The whole premise is that Chuck was the head badass and hero godfather of all the other badass test pilots, but didn't get selected for the Mercury 7 program because he didn't have a college degree, even though he was the only one that truly had "the right stuff" because of pointy headed beaurocrats.
