Tube buffer for driving stuff.

This is just to showcase a little hobby project of mine: Im working on a tube buffer for measurement purposes, to be placed between a source and a long interlink, to drive some capacitive loads.



Here is is the preliminary schematic:



Its fairly straightforward, PC86 into a PNP VAS and a 12B4 to deliver some current all with local feedback.



The FTZ560 seems at glance, a nice device for the VAS.



More to follow.
