RE: Best sounding power pentode/tetrode in triode for SE?

The Siemens F2a connected in triode is a very good tube. It's not cheap, but it's a 10 000 hour tube, unusual for an output tube to say the least, and will last a very long time. It's also easy to drive. If you look at the datasheets, don't be fooled by the high distorsion figures. For some reason, distorsion was measured with a 1,5 KOhm load.

The 6CB5A has been mentioned. I use it in a push pull amp to great effect, but so far not in SE. It has the advantage of being very cheap. Last time I bought some they were only USD5/ea. This tube is Thomas Mayers favourite IDHT output. Lot's of info on his Vinylsavor blog.
