Just finished to bread-board the full tube / high-voltage tremolo and it sounds like this (very happy with the result i might say).
The schematic was modified and an updated schematic will be available soon. If you like to jump directly to action you can go to min. 2:13 but if you like to hear the explanations you can listen to the whole clip.
Schematic (the one on the clip was modified):
