Can you give a part# for the thermal transfer epoxy?

Thanks,

I hadnt noticed a problem.  Its important to note that I use the term
encapsulation loosly.  I'm using thermal transfer epoxy to bridge from the
Temco to the transistor pair so its not a large blob covering the whole
thing.  The outline of the parts is readily visible.

It would probably make more sense to use a larger SMD tempco, but they arnt
so readily available.
