[Amps] Tetrode Amplifier

[Bob Maser]

Having just about completed my modifications on the Henry 4K-Ultra, I am 
looking for another amp project.  I have a source for some 4CX300Y tetrodes 
and I just bought some sockets for them.  I am thinking about finding a 
desktop amp that was commercially produced using goofy tetrodes(or triodes), 
no longer made, and relatively cheap that I could modify to use the 
4CX400's.  Any recommendations?  The ideal amp would have enough room to 
install screen and bias supplies if it were originally a triode amp.  I am 
thinking NCL-2000.  Any out there?

Thanks,
