48-230 Antenna Loop
#16

Thank those who helped me come up with a replacement Antenna Coil, that seems to be working.
I'm working on improving the output of the radio, it's very weak.

I've managed to take several voltages at various points, I know these could vary a lot and I wonder if someone with more experience with tube biasing could see if anything is really out of place here.

BTW:  Local station WLW is 3 miles away by air, while it is tuned to that the reception will reach a reasonably strong level when the digital voltmeter probe touches pin 6 of the 14B6.

Here is the schematic with voltages added:
