Paul,

But then the two High Voltage supply rails need to track well, and all
stages must be working perfectly. It's bad enough with solid state stuff! 
Anyway, far be it from me to be trying to convince someone not to build a
tube-based synth. I guess some people have already gotten bored, having
built the perfect solid state synth. Has anyone priced out the cost and
availability of 1/2 watt and 1 watt metal film resistors and precision 1%
caps with 350VDC ratings recently?  ;-)
