Revisiting the Philco

A couple of years ago I measured the power consumption of the Philco using my Watts Up? power meter. Last week I did the same measurement with the repaired Philco.

The top trace shows the power consumption going up the longer the radio is on, until it's been on about 3 hours. The bottom trace shows in comparison a steady power draw, much lower than before. The little drop at the end is where I turned on my oscilloscope, which is on the same outlet so the line voltage drops a bit. I wonder where the extra 10 - 30 watts was going.

Anyway, that's as good an indication as any that things are working right.
