Anyone inquire to this seller?

Good luck...

One of those would work in my Philco Miss America, whose tube is desperately weak. Wrong side of North America for me to buzz over in my "adequate vehicle," though.

That could be a good deal to someone close, the seller of those NOS Silver-Glo tubes seems to have had no problem unloading them all at $95 a pop.

There's a 12LP4 in that lot too,

Volunteers? My eye is drawn to the 21ACP4A, which someone told me will sub for my Philco's 21BSP4.

Just my luck, that's nearly the most expensive tube on the list (I wonder why?).

Predicta sub?

I dunno offhand what works in Predictas. I need a better tube for my Philco Miss America.
