Vol control ?

As you may know this is a TRF set consisting of a RF amp a detector, and audio out. The plus is it's pretty simple the down side is poor sensitivity.
The cathode voltage on the 43 seems a bit high but it does use a 600 ohm resistor in the cathode. Most I've seen are a bit lower around 300 ohms.
Double check your ant coil and then use a good ant read long and high up.

Found my mistake it was on the 43 tube part 13,14,15 had these wired wrong. To be fair I started this radio when I first started the hobby ran into the dead end and put it on the shelf thinking I need to get more experience. The 5k pot works fine but I need to get one with a longer shaft, not a big deal!. thanks again for helping!
