transmitting tube tester

Anyone have a good schematic for a tester for transmitting tube types (211,845,838 etc).

I've been testing using a bench supply, and watching plate current at around 500v while adjusting grid voltage. I've also played around with using a curve tracer up to 1000v.

I'd like to build a simple jig that can be carted along to hamfests etc.
