Hey thanks for jumping in John. I need all the help I can get with this thing. I've been doing this for about a year and a half and have learned a great deal but this radio is stretching my knowledge of these classics a bit far.
As for the band switch, I had it completely out and cleaned it quite thoroughly. The oscillator is working and I have verified this at least 4 or 5 times now. And as I stated in my "OOPS" post, it is the plate of the 1st IF 7B7 tube that I touch with my DMM lead. NOT the plate of the 1st Det. XXL.
I did check all the resistances on the Ant. Trans. #3 and the Osc. Trans. #13. Only anomally I see is the reading between pins 5 and 6 on the Osc. Trans. #13. This reading S/B <1 ohm and I am seeing 4 ohms. Is this a problem?
Now I will perform these other checks you have outlined for me.
Thanks much,
Johnny
