If you've had electronics training before, you should be OK to
build it yourself.

1. Always always always start with a breadboard. Dont even think
about getting a schematic and then starting metal and woodwork.
The plywood prototype with clip leads is a necessary step in getting
the circuit down and the amp voiced. When its good, the wood and
metal work is the rewarding icing on the cake. :)

2. Cant go wrong with a 400VDC supply. Lots of 720VCT transformers
out there do this. Angela has the best deals going now - Angela
Universal PT or the Marshall/VOX replacement. Also AES has some
like the One Electron BFTB-1.

400V is too much for a 2A3 or 6V6 but just right for a 300B, a
triode connected 807, 6L6, etc.

3. A 5K OPT and you also cant go wrong. Lots of great options.
If you are on a budget, the Magnequest RH60 or RH80. The One Electron
UBTs are also nice.

4. 400V / 5K load leaves the most options open. 300B being a great
option. Dont snub your nose at SE pentodes either...
