[Boatanchors] Converting Real Boatanchor Radios i.e. old marine band am rigs

[Jay Coward]

Has anyone done this: convert a marine band radio to 80 m AM use? Seems simple as many of these tuned 2-5 mHz. Change crystals and tweak a few trimmer caps and retune the plate tank. Many of these have DC/DC power supplies built in so run off +12V power. Maybe add a key jack and a simple bfo? They generally use 12DK6 sweep tubes for output and the higher power ones just parallel more tubes and use dynamotor supplies.
Ideas welcome.
