OK, it's a little tricky, from the main panel run 30A wire to the 30A receptacle, but only use a 25A breaker (the f2000tx amplifier will just have to get by on 25 Amps). tap from the receptacle to the Plitron input. Wire the Plitron's outputs in parallel to a little two breaker box. Use two 15A breakers in the box.
Notes: My drawing lists the Plitron's input at 120V but the output at 115V. It would have been more fun if the outputs were 15A.
We have to wire the circuit as a 30A circuit in order to connect a 30A receptacle. Then we undersize the breaker to connect the Plitron. This needs a warning label in the main panel.
