Not for any rational reason, but -- blech. For whatever reason my emotional sweet spot is for a solid state power supply but all toobs and transformers in the signal chain. No, it's not rational, it's just what works for me. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

That should be the ultimate high-voltage, superfast fet. The emitters (microtips, strange diodes) don't seem to last. -- John Larkin Highland Technology Inc www.highlandtechnology.com jlarkin at highlandtechnology dot com Precision electronic instrumentation

I thought glass was silicon.Or more precisely glass Fetrons. Fetrons were pin compatible JFETs with direct replacement for e.g. 6AK5 12AX7 etc.

Here's a good starting place http://diyaudioprojects.com/Tubes/tubes.htm And another http://www.dynakitparts.com/ Even Amazon is getting into the act. http://www.amazon.com/Stereo-Integrated-Tube-Amplifier-DIY/sim/B005XE3I3E/2 Additionally, there is a Yahoo mailing list called "funwithtubes". Very nice list. Lots of old timers with first hand experience. And the files section is full of plans and schematics.
