Just tried it without the lamp limiter....

Vanode 254v for both Valves

R47 is 1.6V
R48 is 1.0V
left it on for about 60 secs and checked again- same readings.
Hum does seem a bit lower, but is still prominent.

Just thought, as the V9 and V10 have combined cathode/heaters- would fitting replacement mains caps C51 and 52 help?
