Hey, nice looking enclosure!

The bleeder resistors are very high in value. If you want a reasonable time to discharge to a safe level, you should be going a lot lower.

I'm curious why you need to waste so much power in heat and run such a hot unit. What's the thinking behind these resistor values?

It's possible to make a very light, neat, SMPS style inverter for radio HT that can run on a 9V battery for plenty enough output.
