The original ksa-50 used s l o w MJ15003 / MJ15004 output devices with fT of 4mhz, but everyone still loved it. I subbed more recent and faster Toshiba 2SC5200 / 2SA1943 at 30mhz, as well as another pair, so this could explain the better mids? Choosing output devices that are too fast and you have oscillation issues...the group vetted the best sounding output device and I went with it. no regrets.
I did prefer the sound of my KSA clone over a real KSA-250. Builders Bias? Donno.
The KT120 tubeamp does have a bit of feed back (can't remember what I used, but I was true to the original 8417 design. I dropped in (and biased up) the KT120 as the 8417 were expensive and had a bad reputation of self destructing when bias was uneven or pushed. Quite aggravating seeing a NOS $50 - $75+ Sylvania tube red-plate and self destruct in seconds while setting initial bias. But they were great sounding tubes. Extremely easy to drive, so not much front end was required..
