I'm actively scouting for "original" arcade cabs, but from what I've seen so far, I'm not sure what I'm looking for in determining whether it was an authentic cab at one time. It becomes a challenge when the person has done some restoration to the insides. Anyhow, for example so far of what I've experienced:
1. Wooden coin box - I thought they'd be just a plastic tray of some sort and not an actual wood box.
2. Cabinet material: chipboard/plywood, MDF is what I"ve seen. I suspect MDF would signify a homebrew cab?
3. Cabinet sides are laminate coated over the wood.
4. Inside of cabinet painted vs not painted.
Anyhow, thought I just throw this out there for folks who might have experience in authentic cabs.
Thanks
