Lamm L2 Reference tube recommendation

I have the L1 and the power supply has a similar tube complement, 12AX7, 6C19, 5651, but not 12AX3.
I have found that there can be small changes with different 5651's. See what you can find and give it a try.

thanks for the recommendations ;-) I'll give them a try.

Vladimir knows best how to voice his equipment and uses tubes speciific for that purpose. My advice is to go with what he uses as it works best in his gear.

good point Oneobgyn. I was curious because I changed out the single 6922/6dj8 in the M1.2's. I used Amperex Bugle Boy's that made a nice difference - more air and detail etc.. ;-)
Thanks
