Not a steel chassis for sure. IIRC its the one with an upright
plug in chassis. We were still selling them for abt $160 to
old folk that wouldnt go color. Unlike the color sets most
Zenith B&W's of the solid state years used crappy PCB's &
were all Taiwan.
Known for bad vert outputs & many had a hard to see 60 cycle
shading bar that was fixed by adding a heavy ground to
the rectifiers. ( see tech topics). Near 100% reliable otherwise.
