I saw this many years ago on the net and wrote it down. I can't find the original post to give credit where credit is due, so I'll just pass
it along as received wisdom:

Try 6.3 HS5-3481 23 D 3
This is the same as the 6L6 setting. Minimum reading should be 40 and best is 100.

Did that. Pegs the meter! 😕

Managed to get reasonable readings, with a range setting of E, and bias at around 30. Meter reads between 40-50. Looks to have at least set a baseline, that I can use to compare the tubes...

Regards,
Gordon.
