They're supposed to be the closest new-manufacture KT-66 to the holy grail NOS GEC (Genelex) KT-66s.

Also note these amps (the originals) have a ton of negative feedback (off the 16ohm tap IIRC); thereby making them pretty clean.

If you wanted more dirt you could move the negative feedback wire to 8 or 4ohm tap... but remember too much and it may get flubby in a hurry... that preamp
820ohm + 330/250uF combo on Channel 1 is really phat to begin with.

Again, great info.
Always appreciated LLL.

Any more into is always welcome.
