The set uses an all glass CRT, 21FB or 21FJ.  |
I hope not too, but it is not impossible...I put a VERY gassy (Zenith badged)CRT into one of these Zenith chassis and got to watch internal neck arcing and HV rect arcing both accompinied with glow, and spectacular amount of acoustic protest from the horizontal circuits...Set worked fine before and after with a different CRT (I did not run it long enough to cause damage).
