Here's that LM211, probably the most popular integrated in their lineup....32 watts in ultralinear, 18 watts in triode mode. Very easy to bias, very easy to change tubes if you care to. Here you can see the factory EL34 tubes, which are quite quite good, laying off to the sides. In their place are NOS (new old stock) Sylvania EL34's from Great Britain, a vintage new pair from I think 1962. Oh, sorry, for those new to tubes, those are the 4 taller output tubes in the back row, and you want a matched quad set if you do indeed want to swap out. And with biasing, it's only the output tubes you bias, not the input tubes in the front row. On each end are 12AU7's, in the middle are two 12AX7's. After hearing how glorious the Sylvanias are, I'll be swapping the 12AU7''s with CIFTE's NOS from France, and the 12AX7''s will be British military CV4004 NOS. Of course, I wouldn't be doing any of this until the amp is fully run in with its factory tubes, a quality power cord added, a proper amp stand or rack used,
