BTW - The 7JP4 that I got with this set is just fine. So is the one from the Mahogany set. As for the Blonde
Amazingly all the pins are OK except for one deflection plate. The wire broke off right at the glass. That might be a bit beyond my meager skills to fix.
I've been using a 7VP1 from an RCA WO-56A for testing in the meantime.
