Thought I would post the UGLY sisters

Thought I would post the UGLY sisters

These ugly tubes are not easy to combine with anything for a good result, or so is my experience at least...
A failure on my part probably.

Those have their own beauty

Those have their own beauty

Inner beauty. Away from prying eyes trying to peek under their plates.

They are very shy

Maybe, inner beauty that doesn't come out?

When I'm choosing tube I shy away from them. They have secret and rare siblings that are much better.

He linked to them in his post https://www.langrex.co.uk/products/l63-6j5g-gec-shouldered-grey-glass-oval-print-nos-valve-tube/

Thanks. I thought I had quit the L63 game for good since after trying out so many singles I keep coming back to my GEC / Marconi staright bottle and sold off the rest.

A friend recently lent me a metal base Sylvania 6SN7W (with A marking on top) and that tube has such an sense of air and sparkle without harshness that is incredibly addictive lol. It's a bit lean and lacking in the low end though... I wonder if the metal base GEC can be the ticket?

Yes, they do... I'd elaborate, but it's a secret... just leave a single letter hint: J not L

I could get another pair to try in the Envy. But Felix Audio said no.

I have GEC/Marconi ST and Brimar/STC ST bottles, and my MOV/Marconi straight bottle L63 is still a fav. Haven't sold off the rest... because hoarding collecting reasons.

The 6SN7W is pretty special in that aspect. Uncertain even a metal base GEC can offer that same sparkle. Franken 7N7 can get very close at a tenth the cost - racetrack micas, flat(ish) top version. Could summon @bcowen for the full frankenphile info. Have one pair of Sylvi 6J5s that gets close(ish)... but not quite.

Maybe try the metal base Sylvania 6J5. Off hand, I think there are a couple of different types/plates. The Sylvania 6SN7 that came out immediately after the metal base is worth seeking out as well. It's one of my favorite 6SN7, and I might even prefer it to the slightly earlier metal base.

There are a few different GEC/Marconi straight bottle L63. I like them all, but am partial to the black base, grey glass with upturned cup getter. These tend to have a big yellow MWT label. I think these came out after the metal base and before the clear glass version.

Sylvania VT-94D and early fifties taller bottle version metal base are both worth having. I know @mordy is partial to the latter but in some combos I prefer the early version that is somewhat drier which can be beneficial with some tubes. The taller bottle has more 'fruit'. Both are tasty.

If “plate size”matters the Visseaux have no envy problems. I have one quad with a nice pair and a noisy pair. Think I need to suck it up and finally resolder the pins on the noisy pair and see if that helps.
