If I were to do it again, my preference would be to not do the chassis and turret board myself

I bought a blank chasis from tubesandmore.com thinking I'd save $20. Well, when you don't have tools to work the thing... I ended up spending so much more time than I needed to to lay the chasis out and cut the holes.
If you want a better sounding Vox, go by the trinityamps.com layout and guide for the Lightning, and go with their transformers since they're OEM, just pay $40 for the chasis someone is offering in the swap meet forum. I would also buy the premade turret board from the other link I mentioned. It's just a few dollars more than the supplies alone. I believe these two moves will save a day or two of work if you work by hand tools like I do.
It's completely a preference thing.
