Apologies;

The tube I found in the amplifier was / is a*4-125A*. Never trust an 80 
year old short term memory <g>

Additional info: With the power off and caps discharged I keyed my bench 
test transceiver set at app. 20 watts output and with a scope at the 
filament choke at the 3-5400 socket end I manually keyed the antenna 
transfer relay.  Almost the full 20 watts (peak to peak voltage at 
28.700 MHz appeared at the tube.
