Need to replace the tubes in the 834L and 834P. The L uses two 12AU7s and one 12AX7 while the P uses three 12AX7s. Anyone have experience with various tubes in these electronics? I listen to all types of music. Thanks!
I have tried NOS RCA and Sylvania 5751s I got as spares for a Joule Electra preamp in my 834P. Not enough gain. Have been happy with the EIs that it came with and have also had good sound from Teslas although they got a bit noisy after a few months. Tubes should last a long time in the EAR.
Harry Pearson, in a March, 1998 review of the 834L, recommended going to two Siemens AU7s and a Svetlanov AX7. Haven't swapped out my tubes yet given my unit is just a yr old -- so would be greatly interested in your experiences.
