[R-390] R390A help, RT301 current regulator tube

[Studiumtelecom S.Rocha]

Dear members,

I am restoring an  R-390 /URR Amelco serial 1596 and the V505 and  V701
6BA6 do not have the filament voltage, so I would like to know how to
replace the RT301 current regulator tube.  Any other suggestion will be
greatly appreciated !

Merry Christmas  and a much better New Year for all  !

Regards,
Sam Rocha
