Basically a spotlight

Yup thats the original HOT. 121-831 & its a tough SOB !
The fact that it didnt blow with an opened S cap is amazing !
Replaced by an 800- kit then IIRC a 977- kit.
G line is after the recalled sets but when ever I saw
American Radionics I RAN for a replacement. Hold til you
need room. Prob any Zenith 23V of the era will fit BUT the
23" never had quite the pix as the 25V. If one never shows
you will have a great module kit.
