On the Amp? Surely! The 5Y3 GT, for example, is virtually electrically identical to the older four-pin type 80 tube, but with an octal base. In the Amp I pair different rectifiers with the kind of output tubes in each case.
My point is the Preamp may not feel happy with an adapter as this in itself is another source of signal path intrusion. Of course worth trying to compare, but in my book it is not necessary. The 80 is remarkably inconspicuous. The beauty of this Pre is its contribution to body and gain with barely a tradeoff. Part of this achievement stems from the 80's traits. By all means give it a try and please report back.
