I think the tube that is bad is a #80 or 83 something like that. They 
are available but kind of costly. 

More so than the tubes is the condesnsors that will need replacing. 
back then they used paper dielectric caps and they are almost bad 
by now. Might be able to recharge them with a variac. Slowly bring 
up the voltage and maybe the diaelctric will reform properly. 

What I do want to get is exact replacement caps if necessary and 
restore it back to full tube use.
