The PAT-4 was first introduced as a kit along with the Dynaco 400 SS amp. I built many of these on the side while i was working at Bendini building tube amps and i sold them as complete units. I remember back then that depending on who did the build that units could sound different from each other, i estimate that i built and sold over a 100.
Personally i never liked the way they sounded they had what i considered what was to become the classic SS sound that we lived with for several decades.
