Yes on the very first CCT Hitachi put out the value were 1K so the BW went down but the stability went up, and the sounded like the Dr Thomas amps, the first time I got them to work very well was in the Magnum Amps.
Again with a higher voltage drive stage and inductive source resistors 10uH, then Welwyn changed the resistors to Bi-fillar type whoops start again.
And Drain coupled output stage can be a pain so I drive those with large constant current source , lowering the drive impedance and having a fixed time constant. Thus no wild frequency Parrot Sick Oscillation ( I love parrot sick) my young son said that when he was 3yrs old, so I have always used it in his name, he is now a Doctor of Mathematics and 34yrs Sorry Scott he he.
