I was reading a post about tube amps, and got to wondering about something. When I ran a tube amp in my setup (back in the 70s), I always used Sylvania tubes, mostly 6LQ6s. The word back then was that Sylvania tubes worked best for RF. Most said that GE tubes didn't last long because their plate structure couldn't handle vibrating at 27mhz (???).
Tubes were CHEAP then. Whenever the power in the amp dropped off, I just bought a new set.
Down here, there is a LOT of old tube equipment (mostly TVs) still in service. There used to be quite a few shops that worked on tube stuff, but many of the old techs have passed and their stores shut down.
I picked up a Kris "BIG BOOMER" amp a while back ( price was right), but it's just set on the shelf. If I ever get to looking at it, I want to have a new set of tubes, so I figured I'd go buy a couple of sets while they're still available at reasonable prices. I called around, and NOS RCA, GE, Sylvania, Raytheon (even some Philco) 6LQ6s are available.
So ... What do you guys ( Hey, NOMAD! ) think ?? What brand is best for rf amps ?? And why.
