I found two schematics online. One, which is supposed to be for the 200cx, uses Motorola MJ21194 and MJ21193 outputs, the other, which is supposed to be for the 200c is hand drawn and shows NEC 2SD555 and 2SB600 outputs. The rest of the circuit layouts are similar in design, but completely different in the details of implementation and in the choice of devices. The 200c schematic shows a JFET input, while the 200cx one has a MOSFET input.

Do these sound likely?

I've also seen someone on eBay claiming that the 200cx had a copper cover for the transformer while the 200c did not. My unit has the copper transformer cover but NEC outputs, so I'm not sure if this is correct.

I have also seen posts from people that have Sanken outputs (2SC1586 and 2SA909); were these an alternative to the NEC's? If so, which are preferred?
