Sanyo ez 20's monitors (from DK cab) are getting hard to find, expect to pay at least $200. for a used one and hope its rebuilt, if you can find one. They are a good monitor especially after being rebuilt, collectors are snagging them up because they are the only monitor that is plug and play in the DK,DK jr,Popeye, and other Nintendo cabs of that era. Nintendo did everything differently than everyone else back then (not just monitor design), it could of been because they only wanted you using Nintendo parts? The ez 20 runs on 100volts from the power brick, you can't run it on 110 like every other monitor or you will fry it. The audio amp board for DKs and other Nintendo's of that era are built on the ez 20s chassis, all other game boards that I know of back then had an amp on the sound board or the amp was with the pcbs in the game. So you would need an amp and have to do some wiring harness mods to get sound on a non ez 20 monitor. The video signal from Nintendo's of that era, from the games video board is inverted (again a Nintendo thing) so it is unplayable on any other monitor unless you buy a signal inverter. All these pesky issues are why collectors buy and hoard ez 20s, there golden. If you build your game running a factory DK boardset it will be a real headache using anything other than the ez 20. It would definitely cost more to build a replica DK than to buy one outright for let's say $500.-$800. If you went mame, 60-1, or arcade sd board cab you won't have to deal with these issues and it could still look like a DK for cheaper, but it wouldn't really be a DK or be sanctioned for arcade score submittal.
