GE black-plate 6V6GT Test

GE Black-plate 6V6GT test - YouTube

just got these early 50s GEs I am very impressed with them now I really wanna hear what the holy grail RCAs and Brimars sound like lol

I have something like 70 6V6GT and 40 6V6G on my shelf (mostly sorted into matched pairs and quads on my AVO MKIII). I've used both RCA's and Brimars and both are good BUT in my DIY 6V6 PP Amp I run 6V6G (ST Shaped) from the Sydney Australia AWV Factory which are stunning.

As backups for that amp I have some of these from Bob (my local tube supplier). These sound almost as good (I was pleasantly surprised by them).

Got RCA's ina pre. They are wonderful.

that Russian tube you mentioned may not like the stealth heard about how some of them don't like over 400v b+ on plates Id love to get some RCA grey glass or the brimars also heard that Mazda and Visseaux are pretty amazing and pope's

[JRGuitarGuy]

the stealth I measured 420v on plates and about 400-410 on screens so whatever goes in it gets pushed pretty hard lol

Good point - I have run those Russian Tubes in my DIY Guitar Amp at 300V and in my DIY HiFi Amp at 350V (Ultralinear) BUT I have no idea if they will cope with 400V+.

This (voltage withstand) is generally not an issue with old genuine 6V6 because they were often used in B&W TV sets as Vertical Deflection Amplifiers.

Anode Voltage of 350V with pulses to 1200V max.

yea I read that before crazy **** man pulse of 1200v nuts lol yea the old American and European 6v6 can handle 420v no problem but heard about some them Russian variants pretty much would smoke themselves instantly lol the key is watching that current

[JRGuitarGuy]

the 6v6 was built way tougher than the manufactures really let on you know lol

[JRGuitarGuy]

what you posted was GTA version which was rated for 14watts max plate dissipation instead of the GT version was 12watts but even the old GT version most were easily capable with a 400-420v on plates where all the design center ratings were like 300-350v lol and the screens were rated low as hell too seems most of the old stuff can handle it so what the hell is going on? lol with today's technology we can't make a 6v6 thats capable of high voltages? and one that will last more than one year? lol Did Aliens help them build it back then or what? lol I am fascinated how they could build something like that back then with that technology/tooling just nuts lol

[JRGuitarGuy]

this kinda steers into rumors and stuff I have heard about some special coatings on plates and screens that were pretty hazardous to people/environment so basically EPA and whoever stepped in something like that lol No doubt though there had to be some kind of secret going on with manufacturing techniques but them guys must have took there secrets to their graves lol or just the simple fact that when silicon transistors first broke out and they put tube technology on the back burner so to speak lol
