KT77 in a PrimaLuna

We in the USA have not tried them. Adaptive Autobias will allow you, in a Prologue Two, to run a single KT90, KT88, EL-34, and 6L6GC and constantly monitor and keep each tube in a narrow proper path.

The only reason I shy away from JJ power amp tubes is quality. I don't recommend them because the pins are fat, and sometimes not terminated cleanly, and when there are so many good tubes why go with marginal ones? Your mileage may vary.

The good news is because of our Softstart circuit and we don't run the tubes hard you have a better chance of no trouble.
