Hi Alan,
I used to use the valve transmitter ‘Tune and Load’ in band switchable pi networks and no tvi filter, but had an ATU. I wonder if that system simply matched tx to antenna or actually provided sufficient harmonic filtering? We seem to have lost some  of this knowledge in the quest for broadband ‘no adjustment’ rigs.
