It's power that's limited to 1.2 watts, Ik is about 8 ma.

I will bet it sounds great. Simple triode circuits with no global negative feedback make a nice amplifier.

In fact, I have a system that has nothing but common cathode triode gain stages from magnetic cartridge to output, and I love the sound
 
Hello

Here is another tube preamp schematic, it's a low Z output, so maby it can drive transistors output for an hybrid amp.
