Single Ended Triodes (SETs), the ultimate tube lovers dream.

Stage 1 ...

24.18.240.124

... is where you love the SET sound but can't conceive of giving up your speakers, and they are not really efficient enough for typical SET amps. Happens to (almost) everyone. :^)

Push-pull is a different beast. In fact (see the OTL discussion below) it is two different beasts. But I like SETs, so I won't go there...

Comparing the parallel 300Bs with the 6C33, a lot is going to depend on the particular amps. Parallel tubes are prone to a slight smearing, depending on how well they are done and on how well the pair are matched. But the 300B is much more linear, so it will have less distortion especially near the maximum otput. If the 3C33 is linearized by a small amount of feedback (say 3dB to 6dB) that will help, but you will lose just a bit of the magic at lower levels - perhaps comparable to the parallel-tube problems, though quite different. The quality of the output transformer is a major player as well. All else being equal, that could become the deciding factor.

As always, it would be best to live with each amp for a few weeks before making a final decision. Usually not possible, but still one should be aware of the ideal before making compromises.
