21ct55 question
With the sickness of my 15gp22 red gun I'm considering looking for
a 21ct55, preferable with an all-glass tube already installed. But these sets are notorious for HV problems. I recently found one of my old Spellman HV power supplies, a 30 kV at 2.5mA (75 watts) model, and it works well (its regulated). Would the horizontal system in a 21ct55 still work properly if the two HV rectifiers and regulator were simply removed from the set and the focus voltage regulated with Zeners as I do in my CT-100? Or would the resultant reduced load bother the yoke drive too much to adjust? Doug McDonald |
