> I would get some distortion or rattle from the speaker [Image: http://philcoradio.com/phorum/images/smi...con_eh.gif] .
That would be indicative of a loose, torn, or off center cone in terms of a rattle. Distortion could be a number of things. For this check the voltages around the 6A3's, be sure that the grids are at negative 60v or so. You can check the specs for the tube in the tube manual to determine the correct voltage. Could have a bad cadohm resistor or driver transformer. Also check the voltages around the 42 tube for starters.
Any thing I should look out for, considering the type of pickup this has and whether this could work without modifying it too much?
My 116X had a phono jack installed before I got it. It disconnects the detector output and connects the alternative input.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
