6SD7GT datasheet?

[zhyla]

I bought a box of random tubes and one of them, a 6SD7GT, is just the coolest looking tube I've ever seen. I can't seem to find a data sheet for it though. It's not mentioned in my RC-14 or RC-30 manuals. It's a silly thing, but it looks so different than most tubes it just makes me want to use it for something. Think it's similar to 6SC7? It's only one letter different .

A single letter designation difference don't deem diddly (how's that for alliteration?) as the old RIAA-EIA system assigned a designation based on the manufacturer's suggestion based on the last assigned designation. So the 6SD7 designation was suggested by Raytheon - 6SD7 pentode designer as best I can tell - after RCA suggested that 6SC7 be given to their dual triode design. The 6SD7 is a variation on the 6SG7 which was designed/suggested by RCA which is a remote cutoff variant of the 6SH7 which was designed/suggested by, again, RCA, ad nauseum, ad nauseum <grin>.

Aw shucks. Well maybe I'll just glue it on top .
