Yes...I think they go up to 20Mhz (though I just run mine at 4Mhz ....I'm placing modest processing requirements & higher clocks just results in more heat/consumption)

Well, i know a little about electronics...but inductance & the associated magnetism is something I've never had to apply a lot of thought too. (& is a specialist field in itself). i know the basics.

As it goes, the single string sustainer coils I've wound are about 1mH ...520mH seems like a whacking big inductance (you sure you don't mean 520uH?) , but then there's the question of what type of core, wire gauge used blah blah (things get really esoteric when it comes to old vintage components!). Have you a link to the coils in question?
