Thanks!

Default My Tube Regenerative AM receiver

There are some photos of my brass chassis, brass variable capacitors, regenerative broadcasting receiver, 3 tubes: ECL85 pre and audio output, NFB and ultralinear wired, ECF801 (from TV tuner), pentode as RF amplifier and decoupler, and 6X4 rectifier. Power (rear black core and aluminium), and output (in front of the second photo) transformers are home-made, as all coils (including filter choke, back of the supply board). All caps, except the electrolytics are Siemens MAC autoregenerable, and electrolytics are Nichicon 105C. Ferrite antenna. The dial is recovered from old radio, also brass made, and has been several years in the junk box. Note the board with a double line filter to prevent line noise, and the wire almost all under chassis.

From left to right, volume control plus power switch, tuning and "throttle" capacitor, (Regen control). The main tuning coil is the black (ferrite covered) at first plane in photo 2. I have the circuit in pure DOS ASCII characters (in Spanish) with trafos and coil calculations.

Thanks. It is from a (Perhaps) 1920-30s radio.
