This ain't gonna be easy... schematic is at

The schematic doesn't give voltages, but you'll probably want 700VCT @ 100 mA, 5V @ 2A, and 6.3V @ 3.5A. Unless you can find a transformer from an E101, 105, or 106, you'll need a 24V transformer for the "Colorama" dial lights.
Have you tried Gary at oldradioparts.com? If you want to try a sub, it's easier to work with the wrong voltage than the wrong physical size... what are the dimensions?
