[Boatanchors] Bud Radio Frequency Calibrator question

[Dave Hollander]

I found a Bud Radio Frequency radio crystal calibrator model FCC-90 in 
my junk yesterday.

Google search only brings up the later model FCC-90A using a 35W4 and a 
50C5.

Mine is the older model with an octal tube in it. Currently a 117L7GT.
Is this the correct tube for the older unit?
