Dielectric insulators
#5

Thanks again.  I will give it a try.  I am able to control the volume okay.  My body is acting like an antenna when I hold on to the volume control knob.  Like I mentioned before, the volume increases when I am holding the volume control knob, and decreases when I let go.  But I can raise and lower the volume okay otherwise. 

Any thoughts or ideas about what I can use for insulation material to replace the dielectric material in the sensitivity control?  It probably is the same material used in all of the old tuners for adjustments.  Looks like an early thin plastic material.

Here is another question maybe you can help with...I use a transmitter to listen to music on all of my AM radios.  The music comes in very clear.  I have 3 Philco cathedrals, a model 20, 80 JR and 81 JR.  Sound is distorted on all 3 from the transmitter, but clear on normal radio transmissions.  Is this normal on these older radios?  I have an AMT3000.  Maybe too powerful for the older radios? 

Thanks for any comments.

Jay
