[AMPS] Untuned 3cx1200a7 unput ?

[Glenn Biggerstaff]

Hi , I recently acquired a home-brew amp that is pretty much a copy of
an Ameritron AL-1200 except that there is no tuned circuit for the input
, not even  a swamping resistor . Has anyone ever run a 3cx1200a7 that
way ?  It was run that way in the past but I don't know how successfully
. There is room to add a tuned input circuit but it would require a
separate switch for the input unless I am very creative about coupling
the two switches together  . Any thoughts would be welcome .Thanks 73
