[47'Plymouth]

Hey Guys,
a barn find,1947'Tele-Tone Tv,model TV-208 SUITCASE portable
In complete but very rough condition here in the upstate South Carolina
It's has a 7JP4 CRT,but don't have an adapter for my Sencore CR-161
Tester to see if it still has life left in it
I've heard you use test clip on these odd ball tube
Also need a Schematic for it too and yes the pins are very loose
On the CRTs base it I'm scared to move the base!,needs to be re soldered
Does any else here own one
It's a series string set NO POWER TRANNY TO WORRY ABOUT!
