arrangement some without HVSD. Looking back Zenith & Maggy regret not
having HVSD

That being said, am I correct in assuming that my Heathkit GR-2000, with its RCA-design SCR sweep also uses this HVSD scheme? I can't keep horizontal locked on that thing and when it goes askew a transformer on the horizontal out board makes an arcing noise.
