A tube manual and multi-meter set on ohms or continuity is all you need to find an open heater. Compactron tubes, the heater pin are 1&12, either side of the gap.
Re: the tube checker! A Sencore Mighty-mite or other modern tube checker that has Compactron and Novar sockets would do fine.
I bought a full compliment of tubes for my PortaColors, except the 12JF5 for a buck each from ESRC, dollar-days list.
For the damper tube I use a 19CG3 instead. It's a better tube and two extra volts in the heater string is better.
