[Boatanchors] Trying to identify the origination of a real nice heavy PA ...

[COURYHOUSE at aol.com]

Hmmm... thought    the  4cx250  was higher  plate  dissipation   and  some 
other parameters   differnt...

I don't think ceramic tubes were around in the late '40s or  early
'50s.  Back then the exposed anode tubes were  glass.
