I need close to 10 amp for the f mount and 25 ish for the ccp. All that at 2 volts...
It is definitely doable for under $50 or so. There are several methods, but I'm fond of the DIY approach;
1) You could find a hefty filament ("heater") transformer for vacuum tubes rated for the current you need, full-wave rectify and filter the output, and then make an array of paralleled voltage regulators (with current sharing resistors!) to step down the voltage to where you need. At 10A you could use 11x LM317's with heatsinks if you had to.
2) Find a MOT with intact filament winding, check the voltage it is outputting (some are only a couple volts AC, which is perfect) and if it is at least 1.414 x the voltage you need then you are in business! Simply rectify and filter the filament output, and regulate via whatever means of your choice. Just be careful with the secondary output, it is lethal. The filament windings are good for well over 15A of current without voltage droop.
3) Find a mot with a good primary, and then cut away all the other windings. Wind your own secondary as a step down, of just a few turns. Experiment to find the closest voltage to 1.414 x what you need, and be sure to use heavy cable. Rectify, filter, and current regulate. A MOT set up like this can easily supply 300A at 5V.
Or you could look for commerical high current power supplies, like the ones Ham Radios use, and then regulate the current/voltage down to what you need. This is what I do with my 25A 13.8V PSU.
