A 4E27 pentode is rated at 65w of anode/plate dissipation.  The 
filament/cathode consumes 7.5a at 5V.  The emissive capability is about 
190mA in linear service..  A total anode dissipation rating "not to 
exceed 1500-watts" would allow the use of (23) 4E27s in parallel.  The 
Zout would be 560 ohms.  With an anode supply of 4kV and transverse 
forced air cooling, a 4E27 can produce 450w pep in SSB-voice, Class AB2 
g-g linear amplifier service.  .  Hmmmm.  That's over 10,000w output, 
Bob.   We already have a problem with holes in the ozone layer.  With 
amateur radio operators using that much suds, holes could be burned clean 
through the ether.
