Linlai E 6sn7 tubes

@rodman99999 

I assume you're talking about the Sylvania VT-231, the 1st generation of the GT's. They're fantastic, super quiet, revealing, holographic. They dont go very deep but I get the bass extension from other tubes.

Right now there are more VT-231's available than the early 50 GT.

Hi All thanks for your impressions. Looks like the Ken Rad black plate stands up to its reviews based on your impressions.  @invalid  @danmar123 @rodman99999  I am actually getting my  KR black tubes locally here in Singapore.  Just wish o check  if the ones am planning to get  in the link below are the same  KR black  glass NOS tubes you are referring ?

Thinking of replacing my Sylvania GTBs with the KRs along with my Linlai at buffer stage. The Sylvanias are pretty good but lacks a bit of bass which the KRs  seem to have in abundance. Am still running my Linlais (non global ones)  in the gains and if it doesnt measure up, then I plan to remove my Linlais at gains and  combine the KRs with the Sylvanias. 

Appreciate if you can help by letting me know if the KRs black glass in the link below are the right KRs am getting.   Dont wish to get the wrong versions like the Linlais I purchased. You need to drag down the pic as its sold. But the dealer told me he still has stock. Guess its used.  Thank you.

 That's them!

@danmar123  Oh Great! Its cheaper here locally compared to US prices.

I have 2 pair KR VT-231 Black glass and 2 pair VT-231 clear glass. The last time I called Andy at VTS, a pair of black glass was $400. So I bought the clear glass for about $200.

I swear the BG have better bass than the clear, but Andy said that's not true. Outstanding tubes.
