Good evening Kees Koren, thanks for the reply.
The problem is a self-built device and probably with errors.
According to the diagram that I revealed, the 1 tube is at the entrance of the antenna with the green coil and the variable CV for tuning.
The 2 tube is a 150 pf capacitor on the grid that is connected to the tube 1 anode.
The 3 pipe is connected to the 2 pipe by means of a BF transformer.
The 4 tube is connected to the 3 pipe with a BF transformer.
Place the photos of 2 items, someone for pleasure can give me some information on these elements used in the first radios.
Greetings
