    The Dynaco PAS preamps have a DC supply for their filaments. The Dynaco tube power amps do not.

    Suitable power supplies can be found or built quite cheaply for use as an external regulated DC filament supply. Has anyone tried such an outboard one, and what suggestions would you have, specifically regarding grounding such a supply?
