Paraset Power Supply

This power supply is also used with other projects as a utility power supplly.

Paraset power supply.

This one was very noisy so i opened it. 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. This is the power supply i use with the paraset replica.

The power supply delivers 6 vac and 350vdc. With new rubberbands it s fit for fight. I decided to use 12v to my paraset. The power supply is also tested september 15 1953 the power supply is very simple.

A series dropping resistor drops the output of the supply to 250v. It s not easy to find vibrators today. One of my ham radio buddies calls this the paraset mini cooper. 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 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. It has 2 of the 12ba6 tubes for the regen radio and 2 of 12aq5 s for the little cw transmitter. These can be scaled up or down if your b is significantly different. The output is smoothed by a pair of filter capacitors and a filter choke.

For other radios separate forums can be set up ask the quartermaster. The arrows show in which direction the anker swings. The transmitter has the paraset style parallel series tuned tank circuit and seems to load well even with a random length wire antenna. The voltage parameters measured on the receiver section are shown below.

Consisting of transformer rectifier tube 6x5gt and a capacitor. The power supply is very compact in a great box.
