Talk about a never-ending story. The eternal search for a transformer to run the Palomar 300A you just bought from the neighbor's grandpa's basement. Of course the folks cleaning out the house looked at the 300A RF deck and said "somebody will pay for that". Then they looked at the heavy black lump with a 3-foot cable, 8-pin plug and no name. Couldn't tell what it was so it got sent to the landfill .
This iron in the fire is finally getting warm. Bought an industrial steel enclosure that cost almost as much as the big transformer.
The published dimensions tell you the inside clearance. Big enough for the Antek AS-3T275 transformer. Just one problem the lip around the opening is almost big enough to get the toroid inside the box.
Oops.
Angle grinder time. Gotta find my hearing protector first, though.
The small transformer stacked on it supplies 12 Volts for the heaters in six tubes. The big transformer has two 6-Volt secondaries, but they won't supply the full 6 Amps (or so) needed.
Gonna pick up some rotor cable to feed the 8-pin plug.
It's coming together.
Gonna find out if anyone will pay what it costs to whip this trick together. I'll make it open source, so anyone who wants to can duplicate it.
Back to work.
