I don't really plan to do much in the way of upgrading the SP-10. get a decent plinth on it and play some music is the plan.

Anyhow, back to 1210 mods.

I think the psu mods have been taken just about as far as they can go now with the internal regs and a decent psu.
The bearing upgrades seem to be quite good.

The only path I can see at the moment is maybe to stick a heavy platter on it and alter the drive to suit it. I'll have to have a read up on the circuit one day. There is a good chance that it might be limited by the ic's in the circuit.
