Hi,

Also, does anyone know a suitable alternative to those magical
3C85 cores having a diameter of 25; 42; and 58 mm?

At 136 kHz, the material 3F3 is better than 3C85 for power
transformation (lower core loss). As far as I know, 13, 25 and
36mm toroids are available as well as E-E cores in a number of
sizes (for bobbins).  I don't know about 42 and 58mm toroid
sizes though...
