Greetings!
Be warned - complete display boards are intensely rare, and are typically only taken from dead players. And there is very little that can happen to a player to render it that unrepairable.
There is a chance. When I got these last time, a few people picked up spares in case they had problems. I know that some of these people actually had to use them, but there might still be a spare VFD out there. You might want to post on General or For Sale, and see if anyone has a spare VFD left that they are willing to sell.
I will be getting in a bulk order of these around January (current delivery estimate), so that is your worst case. If someone does have a spare they are willing to sell you, I will put them down on the list for that batch. Good luck!
