"Ask Ralph", but the circuit should work for a 6SN7, as is. I just also noticed you can buy an adapter socket that plugs into a 12AU7 socket and provides pin holes on the top side for a 6SN7, for only $10. Search "12AU7 to 6SN7 adapter", and you will see them for sale. The MP1 provides 6.3V filaments as is and that's fine for the 6SN7. I cannot recall whether the 6SN7 needs more current for its filaments, compared to 12AU7, but even if it does, the PS should tolerate it. But again, ask Ralph.
