Default Aleph P1.7 heat sink?

Aside from the obvious PSU mosfet, do other mosfet get hot enough to require heat sinking?

Thank you

The rail voltage is around +60V. The total bias current flow is average 50mA through all six MOSFETs. I.e. total 60*0.05=3W dissipation from the six, approximately.

A question climbs up the question: If each mosfet has no heatsink, could I touch it with my finger more than 10 sec . . . ?
