I couldn't find anything that looks like the safety caps I'm used to seeing, so I threw caution to the wind and powered up this boat. It seems to be fine but I noticed something rather odd: It has a 25VBEP22 which I know is the type of CRT it originally had, and I believe they have extra lead in the glass to handle more HV. However, when I checked the HV it was no more than what I saw produced by a Zenith 25DC56. I'm wondering if anyone knows of any sets equipped with the 25VBEP22 or the 25VCXP22 that normally drive the CRT at about 25Kv.
Also, there's no VRT, at least not one like those I'm familiar with. Might this be a hot chassis set?
