Indeed. I designed several tubed circuits (phono and mic preamps mostly) 
before I got tired of 300V shocks, and switched to ICs.

I've become completely agnostic about different technologies -- in my 
experience, good audio can come from tubes, discrete transistor circuits 
or ICs, the latter being made from bipolar transistors or field-effect 
transistors.

All these technologies have strengths and weaknesses which the designer 
has to consider. For example, bipolar transistors have a current noise 
component that tubes and FETs don't have, meaning that the right tube 
stage, paired with a higher-inductance moving magnet cartridge (like a 
Stanton) can be quieter than a solid-state stage. And so on.

Peace,
Paul
