6L6 or variant

The audiophile interest in 6V6 tubes is interesting. Back when I first became interested in audio amps the 6V6 tube was what you got in Stromberg-Carlson console gramaphones, and similar mass market audio equipment. 6V6 tubes were everywhere except in amps for audiophiles, which had EL34s or better. If an amp used 6V6s it was ineligible for audiophile consideration. How fashons change!

For full disclosure, I had a neat little Craftsman 10 watt power amp that I used for the midrange/tweeter of my second experiment with biamplification, and it had 6V6 tubes.

Kt-88....I just looked at those amps. They get to 20 watts, instead of the usual 10 watts, by using four 6V6 output tubes. I am sure that performance is limited by the small audio output transformer. A substitute would not fit on the chassis unless the power transformer, and perhaps other parts of the power supply, were put on an outboard chassis. An interesting project for someone.
