RE: hot time in the old cap tonight....

This can be a few things, cap voltage rating too low, shorted 45 drawing too much current, thus over voltage on cap, cap installed backwards.. don't like how cap is so close to resistor either, better to not get it so hot.

As a troubleshooting exercise cut cap out of circuit and measure voltage across bias resistor. It should bias up exactly the same, under static (no signal) conditions.
