Hi,The input impendance of the output tubes goes from close to infinite down to 1 á 3 kohm once it goes into grid current.
Ideally the driving source - besides manage the power requriements (peak voltage times peak current at grid) - sould have a source impendance less than 100 to 300 ohm.
My guess is that a SEPP/SRPP/'my follower' 6922 driving the transformer would manage, and as a bonus lessen the DC over the primary of the IT (DC may also be a nasty thing).Give or take some personal opinions :-)
