Anyone used one of the new Tung Sol KT66?

[Scott_F]

I'm about to drop a pair into an Edana. Anyone used them yet? I love the other tubes that factory is cranking out.

don't those have a metal base?

They look startlingly similar to the new production Sovtek KT-66 tubes.



I currently have the sovteks in my Edana, but am planning to put the original groovetubes back in for the moment.

The bases look very similar, but the tube envelopes are different. That must mean that they are indeed different enough. Let me know what you think of the Tung Sols. I may order a pair depending on your review.

From Dr. Z amps posted by Mike himself...the man is a tube amp guru and I would trust this info!

"It has been brought to my attention from Igor Boros, that the new TS KT-66 aren't really KT-66's at all and the metal base like a 6550 will short the bias voltage if the tube clamp touches them.

Thanks Igor for the heads up.

Pin 1 is tied to the metal base.

Real KT-66 do not have a metal base.
This tube looks like a combination of a KT-88 inners, and the outer design of a 6550.

That makes perfect sense! My old Magnavox and RCA 6550s look just like those but a bit taller.

Man Mike and Igor know their stuff!

Glad to know they haven't sent me the Paypal requst for funds yet.

I'm having trouble finding the Groove Tubes KT66HP. I really like those tubes. Seem backordered everywhere.

I love my GEC KT-66 tubes, matched set.

I have heard nothing but good about the Shuguang take on them as well as their KT88 offerings. They really seem to be putting out some quality stuff right now. Their EL34 and 6l6 offerings are among the best sounding new tubes I have heard,

dont love the price

Yea, currently @ $220 +++

I purchased six matched sets back in 1998 and if I remember it was around $150 for all 12 tubes.

You gotta talk to the Tube Tramp... He has all the goodies.

Re: Anyone used one of the new Tung Sol KT66?

tramp who?

Re: Anyone used one of the new Tung Sol KT66?

Terry Kilgore aka Tube Tramp or Sargeant Overdrive on various vintage amp forums. Terry sells tubes, amazing variety of NOS and new, he is an amazing guitar player with a superb ear, so he can really help one dial in an amp to their specific tonal likings. He has taught me more about vintage tone than any other person, so I like to give him a plug. Well worth shooting a note to. Great guy, great prices and all the rest.
