This is a sad read. I bought tons of NIB Sterns for ~10 years with zero complaints for tech support and parts support. In fact, they were the best at that hands down. I called their 800 tech support number more times than I can recollect and had no trouble getting immediate assistance, or at worst a quick call back. Dorothy was great at getting parts out quickly. Lower cost parts were sent out freely with no distributor involvement. Heck, they even gave me tech support on a couple Sega and Data East pins, being they made those titles pre name change.
I'm not sure what caused this, perhaps Covid, but doing away with their live tech support line was a very poor business decision. I know they lost Chaz, who was a legend, but he wasn't their only good tech. Getting tech support via email sucks ass. It is no substitue for having a live whiz on the line walking you through the steps while you've got the glass off on your pin. Immediate diagnosis and immediate parts support.
This massive customer service failure combined with the recent price gouging has me totally out off. I have literally bought dozens and I think I'm all done now.
