[Boatanchors] 75Th's

[W2HX]

I have a Collins 30K-4 transmitter that uses 75th tubes.  Luckily I have a pair. Many people convert these to 100th, the only trick is that there is a maximum clearance for the tube that will prevent it from fitting. So people take spacers to drop the socket down from the chassis to provide the little extra room needed for the taller 100th

Bob, why not 100TH?  Different filament v.?   Socket?  Just curious.
