[Amps] Collins 30L-1 / 572's B

[R.Measures]

Both tubes have the same peak emission ability because they use the 
same filament.  However, 572Bs have a higher anode supply V capability 
as well as a higher anode dissipation ability.
With 1700VDC on the anode, there would be virtually no advantage to 
572Bs for SSB.
