Designing a motherboard to accommodate the T-Reg - please critique my design.

[Sadface]

G'day Guys,

I am brewing up a dual mono Aikido preamp and I have reached the power supply stage.
I have a pair of T-Reg V4 boards to do the regulating duty.

So I need something to provide the unregulated B+ to the T-Regs.
Also I need something to provide a regulated DC heater supply.
For the sake of aesthetics, I would prefer an integrated solution rather than a bunch of separate boards all over the place.
I also don't like screw terminals so I had to come up with a solution to avoid using these on the T-reg

So what I have come up with is a 'motherboard' of sorts with a DC heater supply, B+ rectifier and RCRC filter, and a lovely spot in the middle to to affix the T-reg to.


So here we are:



A few highlights:

• Pours for the high current DC heaters
• 3 Element snubbers for the transformer secondaries (worked out with a quasimodo)
• Hexfreds for the Mark Johnson approved 'belt and suspenders' approach to snubbing
• 2.54mm pitch pin headers for connecting the T-Reg to the motherboard. I couldn't find any 5.08mm pitch pin headers so my plan is to use 3 pin headers and snip off the centre pin.

This is my first attempt at designing a high voltage PSU.
My power transformers have 230Vac secondaries for the B+ meaning something like 325Vdc raw B+.

Does anybody see anything obviously wrongheaded, dangerous, stupid or sub-optimal?
