Bill, I bypassed ALL connections on the rf side of the bandswitch--no better. I have tried a new 6a8g tube no better.
Yes, I see how this radio uses the two trimmers, the outter nut for the lower area of the band and the inner screw for the upper. If you saw the other post, you read the idea about installing a .01 cap before the rf section of the tuner cap. Well I just did that and guess what, that did not even move the place on the dial where the 680 station comes in. This morning that staition does come in stronger that at night (they may reduce power at night) but other stations on the low end of the dial come in louder also. this is with the added .o1 cap installed or not. The radio is still not right as I can touch the grid of 6a8g tube and it will come in louder, I do not get this effect at the upper end of the dial.
