THE LA6NCA TRANSCEIVER, HOMEBREW

I have designed a new tube tester.
It is very easy to use.
You can both measure tubes and listen to the sound in them.

It is made of a fiberglass plate where the various circuits are placed.
The circuits are:
Anode circuit A1, A2
Grid circuit G1-1, G1-2, G2, G3
Cathode circuit K1, K2
Heating circuit
IN circuit
OUT circuit

The tube sockets are attached to the plate with a 3D printed holder.
Mini banana connectors are used for connection between the circuits and the tube.
