Johnsen Receiver Vibrator-Super-Neptun

The Receiver Vibrator-Super-Neptun was produced by the Danish manufacturer Johnsen in Kopenhagen. It was made for the German Kriegsmarine as a second line Receiver. It wasn´t as good as some of the German designs but the need for more Radios gave it a chance on smaller Boats and such. This Receiver is in bad condition but a rare example not a lot survived.

Some of the knobs are missing but they will be replaced soon. Nicely visible on the dial is the magic eye tube. On the right side a Instruction plate is visible.

Here a more detailed picture of it if someone wants to read it.

Here the connector for the normal antenna and the direction finding antenna are located. Also present on this receiver that is missing on the Transmitter are the hooks for the rubber bands for suspension in the air.

Even more connectors and switches on the other side. Including for the Headphones a speaker, Sprechgarnitur and the fuse.

The inside isn´t as bad as the Transmitter. All tubes are nicely visible. on the right side is the build in power supply.

The box on the left side is for the antenna.

Inside is a sticker very neat.

Here a closeup of the Power-supply it uses a EZ2 rectifier tube and a Vibrator for 12V. The Vibrator I have is very weak and only produces about 70% of the needed Anode voltage.

On the bottom almost all the capacitors are replaced. This was already the case before I got the Radio. I just replaced them again because the old ones had been in contact with water. Sadly I didn´t have the original capacitors so I couldn´t use the empty shells of them to hide the new ones.

This is the bottom side of the power-supply. A loot of the cables have been replaced not by me but by the previous owner sadly. I did have to replace on of the switches that was broken but I had a original one laying around so the change is not visible.

Some of the old capacitors are still inside the radio (the square ones) these were not damaged by the water.

Here the oscillator and all the Bands can be calibrated. A loot of work when done right. One of the coils is sadly broken and I have not found a replacement so not all Bands are working.
