I put in a pair of EH KT90s in my D60 over the weekend, and they sounded great. Imagine crossing a KT88 with an EL34 and there you have it. Deep tight lows like the 88 with the mids and sweet top end of a 34. Anyway I messaged Fryette support and they said that it's fine to use them, just to bias them within the same range as you would with the 88s. Also, KT 120s are safe as well to put in the VHT/Fryette amps. That's my next experiment...will let you all know.
