If you're an audiophile looking for a high-quality sound experience, Teslavak tubes are definitely worth considering.

Recommendation:

If you're willing to pay the premium price and can find Teslavak tubes that are compatible with your amplifier, I would recommend giving them a try. The improvement in sound quality may be worth the investment, especially if you're a serious music enthusiast. However, if you're on a budget or have compatibility concerns, it may be worth exploring other options first.

Details:

Not sure why I let em sit so long these were written up in strophe and mentioned in the article on the comm 275 and they stated if you liked the Richardson tubes that these would make the amplifier sound even more stellar and they were right. If you are lucky enough to own a comm 275 c22 these would be for you I would imagine they would sound stellar in any that uses kt 88's. I also tested each tube in a b k 600 tester and they were all at I did number in black the socket locations 1/4 as you can see in the pix.

I never was a fan of Richardson tubes and I am sad I never really enjoyed them. The 275 is about to be sold so I really do not need them so here they are. There are 5 Teslovak kt 88s tubes here that I bought in the 1995 range. The reissue Benelux kt 88's do not sound near as good as these Teslovak.

To the 48 states and well packed and insured. I bought them with the intention of using them in my commemorative McIntosh 275 which I put them in tonight to test them to make sure they sounded and operated well.
