P.S. the proper PA tank coils for ARC-5 transmitters are:

500-800 KC    9226
800-1300 KC    9231
1300-2100 KC    9234
2100-3000 KC    9291
3000-4000 KC    9292
4000-5300 KC    9292
5300-7000 KC    9294
7000-9100 KC    9295

Don't forget the ceramic tubular, C-72, which is usually removed 
and lost the same time as the PA coil in ARC-5 transmitters.
It's the plate DC blocking cap, 400 pFd, tested at 1800 volts.
You really must have the correct cap, as this one is 
specially speced to handle the modulation peaks and compensate
for temperature changes in the cap.  
A cheap cap will change value with heat and thus 
change the PA loading and pull the Master Oscillator.  
It can even lead to FMing if the cap is really bad.
I'll try to find the right one in the stash.
