Guys, I'm bidding on a Sony C-37A on eBay. The guy doesn't have a power supply for it, but has the schematic. I've dug up schematics on eBay, but am stumped as I don't know what type of power transformer I'm looking at, as well as finding out the values for the diodes. I'm just not good at figuring out the calculations. (OK, I don't really know how.) I know I could build this if I can just get the parts right. Please help.

The cryptic hand written notes I've found on this so far indicate the PT outputs at "250-0-250v @ 5ma, 6v @ .6a, 10v (6v top) .5a". Sorry, it's hard to read off of a gif.
If I need to do this with separate trafos for each, which are which? Also some of the caps are marked "2000" and "20". I'm not familiar with caps of those values. I can find 1800uF. What the heck am I missing?
