[Amps] Thunderbolt clone

[TOWN COUNTRY FLOORS Owner]

Gentlemen,

I was trying to find a thunderbolt for the AM station That just about 
duplicates my dads.  A Viking Valiant and a NC-183D rcvr.  I haven't found a 
thunderbolt so I was thinking of making a psuedo clone ie. find an old 
Ranger and have the holes in the front filled and use the cab to put a amp 
in.  I was thinking about using a pair of 4-400's or a pair of 3-500Z's. 
Where can I pick up a good schematic for either pair of those tubes.  This 
will be the first thing I have built since Navy 'A' school in '59 so I 
better find a local to help 'elmer' me thru it.
