€   Methinks:
The designer seemingly:
1. did not realize that a tuned input circuit is needed for g-g config.
2. did not take the mfg's recommendation for vertically mounting 
vacuum-caps.
3. did not experiment with HV-RFCs to determine that sections which need 
to be
   decoupled from each other do Not decouple if they are mounted end to 
end.  
4.  supposed that tank conductors need be no larger than what is needed 
for 50/60 Hz
    applications  -- i. e., he/she seemingly knows not of RF skin-effect. 
 In a 3cx3000A7
    amplifier,  tank circulating current is c. 30A (approx = tank-op-Q  x 
 I-anode).  30A at
    14MHz heats like approx 60A at 60Hz.  
-  However, the tank looks like it receives forced air cooling.
