Tube amp for my car

[wa2ise]

As mentioned above, another approach for getting some tube sound in the car would be to use a tube buffer stage ahead of a SS amp. And the tube buffer built using say subminiature tubes intended for fighter jets or guided missile service. Say a pair of triodes in cathode follower connections. And you may be able to take apart an inverter to get at the high voltage DC before it's chopped into square wave AC, to get the B+ for the tubes.
