Now that I saw that the 80 is the tube for it, I will leave it in. Boy does it get hot: this one is the small cylindrical envelope ny Ratheon and I seared my fingers a bit trying to take it out.

The speaker sounds beautifully, thanks Rich!

Now the only band I hear is the BC, the other two are silent.
Another thing, the AC hum. I checked it and could see the wire connecting the wiper of the volume pot to the output cap is picking up the hum as I move my hand near it. Could be due to the increased value of the pot. I think I will try shielded wire. And the wire runs exactly where it did before, so no new influences. Shielding might help.

Will see later.
