Rob,

Yes, that is a good point about detuning some of the sensitive circuits. Sound output circuits is what got me going on this because I have two sets that are suffering in that department. I have thought a few times about attempting to fix my Predicta's sound socket, but usually I end up deciding not to because that PC board looks weak and brittle due to the heat, and also the fact that taking apart a Predicta Princess is such a pain in the butt!

In addition to the heat emanating from the tube itself, there is also the fact that some of that heat is traveling from the heater though the tube pins. I would think that adding the socket would cut down on the heat at the solder joints at the original socket and PC board.
