Quoted from smokedog:Does being heavy equate to quality? Put 50 pounds of bricks in your Stern cabinet. Let us know how the quality improves.
Stupid statement. The added weight is a result of the quality improvement, not the reason for it.
Let me spell out a few examples for those who are slow on the uptake. Note that WOZ is a widebody. Bigger pf, bigger cab = more weight. But that's a design choice, not necessarily related to quality, so that is one factor that adds weight. But for the quality factor, we have this:
WOZ has 11-ply plywood (higher quality) that is also a bit thicker than standard playfields. (There was an early change of some hardware for the increased thickness.) Stern *downgraded* to cheaper 7-ply (from the former 9-ply standard). Thicker plywood = more weight, plus the added quality of more plies.
Pretty sure the WOZ cabinet is also made from the same plywood. Can anyone confirm? If so, stronger/better cab, better quality. And heavier.
WOZ has a lot more "real" toys on the pf compared to current Sterns. I'm not talking about cheap plastic off-the-toystore-shelf glue-it-on crap. 2 mini-playfields, each made of better plywood. More motors and coils and magnets, all of which add weight. Metal rail guides and brackets (WMS style) seem heavier than Stern's. Someone reported that WOZ plastis were heavier/stronger than those used by Stern now. I can't personally confirm that, but I wouldn't be surprised.
Hi-res graphics printed on wood, with ample clearcoat. Probably doesn't add much weight, but is better quality than cheap printed decals slapped on a flimsier cabinet.
Audio system: *seven* component drivers, plus more bracing in the backbox to support them. As opposed to 2 cheap-o single-driver speakers in the Stern backbox (yes, even on their "top-of-the-line" LE models). Add in a real audio amp with crossover (OK, not a huge amount of weight there but big difference in audio capability/quality).
The "brains" include a real pc motherboard, real memory, etc., and all conveniently located in a detachable metal cage box for service/testing. Probably a bit heavier than Stern's current board system, definitely more capable. (It can run HD video and quality music, etc.)
Playfield support? WOZ has the killer full-length "sled runners" (like Pin2k did) -- SLide it out to any distance and all components underneath are protected. Or, unplug and pull the pf out, sit it on your floor or bench to work on the pf with unobstructed access. Stern? The standard sheet-metal sliders weren't cheap enough, so now you get a useless pair of little plastic pegs. Not only can you not really work on the underside of the Stern pf without lifting it all the way up, but if those pegs get knocked off the little lockdown rail, the pf will drop and you might crush some components. Handy? No. Protective? No. Cheaper and lighter? Yes. Advantage WOZ.
I'm sure there are more examples; I've only explored the inside of a prototype. To address your comment: WOZ doesn't have better build quality because it's heavier. It's heavier because it has better build quality. See how logical reasoning really works?
