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

RE: Venturing into SET active system. Does a 45 have enough power?

"12 ohm 104dB/W driver should be better for dynamics than an 8ohm 104dB/W driver. Right?"

Nothing sets in stone here! Depends on your speaker's true impedance curve, the amplifier circuit, transformer load to the output tube matching and the Output transformer's true impedance ratio.

This requires try and true approach and listen to the speakers at different tap. Generally, a higher impedance 16ohm tap will provide almost twice the voltage of the 8ohm so it sounds louder so it may sound a little more dynamic at the same amount of volume at 8ohm but some music may suffer.

And depends on the type tube and and the amplifier circuit, using the wrong impedance tap for a long period of time may shorten the output tube life due to the more stress placed on the output tube. And people have to wonder why they need to retube often?

45 has a really good tube life for normal use!
