I realize that what I am about to recommend is expensive -- but any amplifier designed around the 6L6 will be transformed with the the KT-66. The best after-market KT-66 in my experience is the Shuguang product as it will get you the closest to the Genalex KT-66. However, there is nothing on this earth that compares to the original Genelex KT-66 with the carbon-coated bottles. I have that experience with them and I must say it was eye opening as well as ear opening.

You mean these?

Trying out Russian Gold Lion KT88s. They are very detailed and dynamic but little thinner mids and bright top end. Doesn't seem like a good tube for 511Bs.

The Treasures are probably better than the standard Shuguang KT-66s because of the carbon coating, but the standard Shuguang KT-66s are damn good and less expensive.

The Russian KT-66s are OK, but the Chinese make a more musical product that gets close to the Genalex.

15 year old Shugaung KT88s which came with Cary Superamp sound much better than the new Genalex KT88s in my system. Shall try the new shugaungs.

The "new" Genalex KT-88s are nothing more than branded Russian tubes from the Reflector plant. When I had my Jadis I made the mistake of trying the Russian Genalex tubes. UGH!

It made the Jadis sound like a 1970s Japanese receiver.
