Specs on the Sharp chassis are low impedance vertical yoke (15 ohms), 8 pin (small diameter) neck, 100 volts isolated power, audio amp and video inverter built in.
A Wei-ya 2420-S (with contrast control!) or 2620-S (no contrast control) will work picture-wise and has a switching supply for operation on as low as 90 volts AC. Does not need an isolation transformer.
A Wei-ya 1220-S (120 volt AC only) will work, but reqiures an isolation transformer.
I did one of these Sharps with a 8liners.com (made by Jen Shinn) replacement chassis because it had to work in a Nintendo cabinet on 100 volt power. The Nintendo cabinet I used was converted for Jamma boards so naturally I did not need video inverter or amplifier board. This came out very nice and had a great picture, however the Jen Shinn already needs a capkit as it is looking crappy now. I'm sure if I replace the el cheapo original capacitors it'll look great again.
Since replacement flybacks are not available for the Sharp chassis, the only hope to be able to use this monitor is to get a universal replacement chassis like the Wei-ya or Jen Shinn.
