Folks,I want to (at least begin) wrestling with some design parameters for a project to build an OTL amp to drive the panels of my Quad 63's directly (no intermediary transformers). I realize that it will have to be a PP design with KV's on the plates. Need some enlightenment? How much power/current is necessary. What output tubes to use? Do output tubes drive resistors; chokes??? ANY thoughts appreciated.
Thanks in advance.
Follow Ups:
There is a design (called the "electrostatic beast", no less) in the book "Valve amplifiers" by Morgan Jones (in the 2nd edition at least). That was a direct drive design for home made panels, probably worth looking into.
.............but just remembered it is probably not an OTL design....sorry......forgot which bit of the asylum I was in, somehow...
Audio Amateur had an article back in the early '70s about just such a direct-drive amp for electrostats--might be worth re-visiting.
