[ARC5] Tube Equivalents VT-52 VT-62

[Dennis DuVall]

Sibley also lists it as a  2C45 and describes it as a  “45 with a 7 volt filament”
Rare and pricey tube and it would be prudent to approach the application of
7 volts to the filament with caution, i.e., maybe 2.5 volts first, then 5 volts while 
carefully observing just how the thing is lighting up.
