GG mode needs a fair bit more drive than grounded-cathode.

But as said, it gives good linearity and circumvents the need for neutralisation.

I'm guessing the wanted mode is SSB because of 'Linear' in the title.

6L6 and 807 are common in the UK. American sweep toobs are fairly rare. The PL509 and PL519 was the common line output family here and there are HF amp designs floating around using them ( EG: 'Frinear')
