Solid –State
A purely solid-state J-FET
based circuit of fully-
discrete Class-A topology
Tube
The J-FET circuitry is
switched to the valve
Class-A section based
on two GE5670
Tube+
Negative feedback to a minimum.
Greater amount of the tubes’ natural
harmonics is produced (even order
harmonics dominate).
