Okay guys. Sorry for the delay..
Here's what I gots..

It WAS due to reverse voltage. I'm not happy about it, and TEMPTED to take OUT the Power Plug altogether and make it so the board HAS to run on Empeg Power...(Ideas? Thoughts? I do NOT wanna see a news report on CNN or BBC because someone burnt down an apartment complex because they didn't read my warning.)

Assembly instructions have been finalized. A copy will be provided with each kit order, and is downloadable (URL coming soon.)

I will resume sending kits out. Once all outstanding orders are sent, I'll resume sending e-mails. Etc, etc.

A consideration, in the future, is to offer a second revision of the board. However, right now, I don't have the money. There's a few other things I'd like to change, for cost-saving and features, sich as:
1. Adding a diode, so if someone DOES plug in a rever-power adapter, it doesn't burn down the house.
2. Changing the DPDT switch to jumpers. This way, someone could use a little header and 'intercept' signals to/from the VFD.
3. Trying to get it on a slightly smaller PCB.

Me.
