There's the 6112 twin triode submini tube, somewhat similar to a 12AX7. With a reasonable mu around 70 IIRC.

With wire leads you could just solder into the circuit, so no tube getting loose issues, and it's designed for mobile work.

I had not though of opening the inverter and removing the chopper fets. Brilliant!

thanks.

All you need to do is ad the 2nd and 4th order harmonics to give it the tube sound.

That's the ticket.
