Well, the classic one is a simple half-wave rectifier and OA150 voltage regulator for 150 plus or minus 5V odd.

That was fine for my converter.

In terms of vintage designs, you could easily mod the design that I posted for 4 metres instead of 2... take a look if you like? Very sensitive and selective little thing...

IF you want a more flexible power supply, try one like the one I've uploaded. I have used a very similar one in the past for a home-made Nixie tube clock. You can run it from a bench power supply or a battery.
