The power supply is also tested september 15 1953 the power supply is very simple.

Paraset power supply.

This is the power supply i use with the paraset replica. Power supply for mk vii this forum is all about building and using world war ii spy radio equipment in particular the whaddon mk vii paraset. The power supply is very compact in a great box. I decided to use 12v to my paraset.

One of my ham radio buddies calls this the paraset mini cooper. The rubber bands who kept the chassie in the holder had vanished. It is built on a small bread pan i use these to sort small. The b power supply uses the standard full wave center tapped configuration.

The homebrew power supply built for the project was only able to provide 295 volts which is a little less than desirable but enough to provide a solid 5 watts of qrp output from the 6v6 power oscillator. This power supply is also used with other projects as a utility power supplly. A series dropping resistor drops the output of the supply to 250v. A 5y3 gt or a pair of 1n1007 silicon diodes if desired is used as the full wave rectifier.

It has 2 of the 12ba6 tubes for the regen radio and 2 of 12aq5 s for the little cw transmitter. With new rubberbands it s fit for fight. The transmitter has the paraset style parallel series tuned tank circuit and seems to load well even with a random length wire antenna. For other radios separate forums can be set up ask the quartermaster.

The power supply delivers 6 vac and 350vdc. The voltage parameters measured on the receiver section are shown below. The arrows show in which direction the anker swings. This one was very noisy so i opened it.

These can be scaled up or down if your b is significantly different. It s not easy to find vibrators today.
