Terry, I relied on the chassis gnd for my numbers, just tried the cap neg for comparison; my antenna was always connected and I checked the 3 tuning cap trimmers again (yep WDAS 1480). With the shield off, touching the 44 RF amp tube cap results in a slight reduction in reception, touching the 36 detector/oscillator cap results in a noticeable increase and touching the 44 IF cap eliminates the signal. Is all this as it should be? For now I will leave the tube shield off and enjoy the good sound, but something still needs fixing (or not)!
