Title: 10Y, 807 and 2C53 tubes
Post by: SLW on January 20, 2013, 04:00:38 pm: Cleaning out more tubes that I will never use. I have a Sylvania 10Y, a "Taylor Tubes" 807 a Sylvania 2C53. Is there any demand for these out there? If they are like old TV tubes and useless I will just chuck them. Otherwise I will try to sell them. Anybody know anything about these things besides what the data sheet says?

I am a little curious about the Taylor Tubes brand. If you have ever heard of it tell us about it.

The "lauren" amp looks like a tweed princeton but with the 807 tube instead of the 6V6.

Thanks again for the input. I am going to try and sell the 10Y and 807.

Post by: HotBluePlates on January 21, 2013, 08:30:18 am: An 807 is essentially a 6L6GB with a top cap for the plate. Keeping the plate terminal away from the other pins allowed the use of higher plate voltages in some circuits.

Ham radio sales stopped in early 1942 and all bottle-suckers turned to war production. I'm not sure if Taylor offered the "generic" tubes to hams, but obviously their war production was The Usual Types, and of course RCA/GE had to allow (license) such production for the duration.

I think the Taylor-invented tubes mostly start with T, such as T-20. 807 is clearly RCA-invented, but was probably in high demand, and something Taylor could produce to help with the war. I don't know if Taylor kept licenses after the war, or even how long they lasted in the post-war era.

The Taylor name survives as a re-brand of Chinese bottles. No real relation.

Post by: kagliostro on January 22, 2013, 04:42:51 am: Few days ago I was reading about the "new" KT120 who has a strong 60W plate dissipation

Yesterday I've give a look to the first link PRR posted and I was smiling to myself

looking to this old tube, and it isn't the fatter available :smiley:

only 125W plate dissipation

510W audio with two tubes :icon_biggrin:
