The H/K Cit. 2 is 1 of the very best PP KT88 amps, ever. Unfortunately, we can't try replicating it, as the "super/duper" O/P trafos needed are unavailable. BTW, the H/K Cit. 2 is a 32 Kg. stereoblock.

All it needs is a broken one delivered to a skilled winder. I have one like this. Just no project to plug them into yet. He who wants a set of Citation II outputs, call Heyboer and let them know...I'll take care of the rest...:)
cheers,
Douglas
