Hi.Bsing on my suggestion using 6SN7, I think you can try 6N1PVI (or Russian 6H1U-BN) to replace 6SN7.
From my limited specs on this Russian twin triode, with both tubes opersating at 300V Vp:-
(1) u=35 (u= 20 for 6SN7)
(2) cathode current: 25mA (20maA for 6SN7)
(3) Wp=2.2W (3.5W for 6SN7)
(4) max Vk-heater=+250V (+200V for 6SN7)
(5) Cgi=3.3pF (2.8pF for 6SN7)
(6) Cpo=1.75pF (0.8uF for 6SN7)You may like to drop B+ from 350V to say 300V for 6N1PVI to ensure not overpower its plate dissipation.
Good listening
