JVC fired us just before that model came out and their manuals were too expensive to buy so I just borrowed them when I needed one or crossed them over to Zenith or, later, Philips. Does this model have the power supply in a metal box at the left rear of the unit? Does anyone know the cross to Zenith or Philips? I have all those manuals.
