Zenith never used that HVSD scheme. Off hand I remember RCA,
Hitachi, Panasonic using it. The Zenith CC2 & flat chassii had NO HVSD
circuits. The dept of HEW approved both the S caps in parallel & the
4 lead caps for X-ray protection. Most mfg's both US & Jap in the mid 70's on their top of line sets copied the Zenith fero-resonance supply & cap
arrangement some without HVSD. Looking back Zenith & Maggy regret not
having HVSD
