"I don't have a center tap on my 6.3v filament supply, but I guess there is a way around that, for the 12X7's."
Same here. I used two 100 ohm resistors from each side of the winding to create an artificial center tap. Rather than grounding them, I applied about +75V (voltage divider from B+) to help prevent hum.
"Also don't know what difference my tube type rectification would have, if any."
I added a separate 5V filament transformer to mine and used a 5AR4. Your 5Y3 will work just fine. SS diodes are one thing I don't like about the Marshall design.
"I don't think Two 6V6's in push pull could deliver anywhere near 50 watts"
A pair of 6BQ5s is typically used to create what's known as an 18 watt amplifier. 6V6s fall into the same category, although in fact they output a few watts less. There are schematics scattered around the 'Net showing many Marshall-type builds using both tube types.
Good luck!
