Never seen one with square mica until now.

All three valves I have are square mica and ladder boards.

Shape of mica doesn't have effect on the sound, it is basically the construction shape of the plate (anode) that makes the sonic character of a tube. For clarification, BGRP means black glass round plates, it has nothing to do with the shape of the mica. Micas are not plates (anode) in case you are confused. What you have there are called flat ladder or ridged plates.

thanks for the clarification. So, could anyone tell if there is a difference in the sound of the TS 6f8g Stair Boards and the TS 6f8g Round Boards?

Plates. Not boards, plates. Please....those of us with tube OCD are getting carpal tunnel from gripping our chairs so tightly.

So.. anyone has the Linlai Elites to compare against the NOS stable?

I currently have E-6SN7 and E-6SL7 in my Willsenton R8, (using EL34's). I find the Linlai very quiet and fairly linear so far, just a little of tube magic holography sprinkled in these. The lack of background noise was surprising and may be a significant factor when comparing against NOS. I still have a few days to break in the 6SN7's. I have already tried some NOS Sylvania, Brimar, GE, some Russian stuff, etc.. but I think my final selection will either be the E-6SN7 or new production Tung-Sol 6SN7GTB (which seem a little more forgiving on the top end.)

Hmm.. do share more btw the Linlai and Tung-Sol when you've burned in. I'm wondering if it's an worthwhile upgrade for my HA-300ii

Hi,

I've just received this two 6SN7 brand Rad Tel (?)... is there anybody that has an idea about possible manufacturer? year 1962 week 22?

 

[triod750]

My guess is that Rad Tel stands for Radio and Television and they were sourcing their tubes from xxxxyyyy . Haven't got a clue as to who xxxxyyyy really were.
Enjoy!

Have just rolled a pair of Philips E80CC for a few days, thought they sound really good as 6SN7 in my amp until I put in the ECC31 and wow...ECC31 wins hands down, no question about it. I am just wondering...has anyone compared ECC31 to EF80, EF86 or L63? Please share your thoughts if you do, thanks!!!
