April Stereophile Sam Tellig review of Classic 60SE

[Joe Appierto]

In the latest edition of Stereophile there's a very favorable review of c-j's Classic 60SE amplifier by Sam Tellig. He goes into some nice detail, as well, on the KT-120 tube. It seems that Messrs. Conrad and Johnson like this tube a great deal in their amps.

The LP60 SE as well as the LP125m SE are also rated Class A in the same issue of Stereophile.

One interesting piece of information I got from the review is that the legendary GE 6550A also had a filament current of 1.8A. Since I used these in my Beard 10 years back it means I can use the KT120 in the Beard as well. The Beard should squeeze more than 100w out of a pair of these tubes. I was afraid to try them in the Beard until now.

Yes, even with the assurances from the members here and Ed from c-j's Customer Service, it was good to read that the GE 6650A, which the Premier 11A was voiced with, drew that much heater current.

Interestingly, if I'm reading the data sheet that Tube World has reproduced from the original Tung-Sol 6550, their 6550 draws 1.8 amps as well.
