That's one advantage of choke loading, output voltage can swing higher than B+...

Use an OD3 and drop half of the 150V across the plate resistor. Stay 100% obsolete technology.

Don't get sucked into that newfangled thinking. It's a commie plot.

You can also use a current source in the cathode and rely on Mr. Allen and Mr Bradley for plate loading.
