Sunn used complete "Dynaco assembled" amps in their early guitar amps. I have a MKIV from one with the same A470 OPT. Later models used the Dynaco circuit on their own chassis. Might want to skip the Ultralinear connection tho, Fender used UL OPTs in some of their 70s models. They are NOT the sought after models.

I think that's a matter of taste. I'm a (frustrating) jazz guitar player, so I look for a warm but clean sound, rather than crunchy. I remember playing through one of those late '70s Twin Reverb amps with the pull-out master volume (get rid of it!) and the UL OPT. It was great with a hollowbody jazzbox like Gibson ES-175. But that type of sound would be unpopular on the broad market, as the amp simply refused to go into "Mesa Boogie mode"...

The cool thing about building your own guitar amp is you can tweak it to your heart's content. I especially liked playing with the response of the tone control stack.

Lots of fun.
