[sdiy] expo pair "heat shield?"

[Roman Sowa]

A dab of hot glue is not the best heat conductor by far, and you want 
the transistors to share their inner warmth so closely. It's good to 
help them hug each other by the force of heat-shrink tube around them.

IMHO unless it's all (transistors and tempco) dipped in thermal epoxy 
and covered all around by 2cm of insulation, there's no gain in doing 
anything more than the heatshrink tube trick and tempco glued to them by 
thermal-conductive glue.

Large blob of thermal paste or whatever has bigger surface and can be 
easier affected by any random airflow, which could possibly lead to 
worse results than no thermal compound at all.

AFAIK there is thermodynamics specialist in this group, so he could tell 
more. I'm ready to hear how wrong my assumptions are.
