I want to thank everyone for all replies until now.. More than I expected!
Many options are "on the table"...
The easy way is...unbypassed cathode resistor for 6EM7 high µ triode for lower gain (a bit over 20dB).
If 6EM7 high µ triode is not used:
Around µ=20: 6SN7, 6J5, 6C5 (similar to 6J5 with slightly higher plate resistance and lower transconductance), 2C22/7193...
Around µ=30: 6DJ8, 6922, 6N23P...
Those two last categories could be used with CCS and LED biasing.
Also, a different dissimilar triodes tube with different specs is possible, like 6DE7. However, how is it linear for an adequate gain?
Finally, some guys suggested a completely different approach. Even if their results are quite good, it wouldn't be my first choice.
