Mounting LU1014D

Magura when soldered to a copper block like you used do you have any idea what the
thermal resistance case to sink will be.

No, but it's low.

Before I used this method, one of my "test the limits" setups, would send the temp of the JFET up on the wrong side of 150C. With the copper block, it's below 100C, and (embarrassing, I know) limited by the capacity of the heat-sink.

I have silver solder. Do I need anythink but the blank copper and a powerful solder iron???

I just drilled and tapped two holes flanking the fet. Then cut a small length of aluminum and screwed it down with a silpad under the fet.

So did an amp different than a zen variant ever come of this?
