Ok. I have been reading back on old posts.. There was a discussion between a few members about "Econoquick"..

This design is meant to leave a few volts at the heaters when the tv is off, not half, or full voltage. I have a feeling that Sony designed this device while the energy crisis of the 70's was in full swing. Sony probably knew something.. If they couldn't get away with half voltage cause of the guidelines introduced then, they could with econoquick. Something at least had to be there at all times to keep the cathodes clean. My theory is If a Trinitron CRT is put into use, it cant sit for a while dormant with no filament activity or the cathodes will become corroded.. The fact that people probably may have been worried about energy consumption, they may have unplugged the set often while not in use, possibly drastically reducing the life of the CRT. This set set for 25 years stated by the previous owner. She recalls that the picture was perfect before it was put out of service just to replace it with a projection tv. It sat in the garage since unplugged.
