I agree, which is why my plan is to use the radio/phono switch to switch any mod in and out. I used that switch to simply add a resistor between the last RF and the audio amplifier, and it kind of works, but I'm not happy with it. I have another plan to try later today.
I honestly don't know how the signal is getting in. I can remove the first three RF 26 tubes and it still plays and tunes. Because the volume control is a bucking coil on the second RF stage, removing that tube eliminates the volume control
The radio chassis is fully shielded and only about 2/3 of each of the tubes are above the shielding pan. I placed soup cans over the tubes and it has no effect whatsoever. There is a longish umbilical cable from the power chassis to the radio chassis, but it's bypassed both at the power chassis and the radio chassis, so I'm not sure what's going on.
