Paraset Power Supply

A 5y3 gt or a pair of 1n1007 silicon diodes if desired is used as the full wave rectifier.

Paraset power supply.

The power supply is very compact in a great box. It is built on a small bread pan i use these to sort small. It s not easy to find vibrators today. It has 2 of the 12ba6 tubes for the regen radio and 2 of 12aq5 s for the little cw transmitter.

One of my ham radio buddies calls this the paraset mini cooper. These can be scaled up or down if your b is significantly different. 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. The voltage parameters measured on the receiver section are shown below.

The power supply delivers 6 vac and 350vdc. Consisting of transformer rectifier tube 6x5gt and a capacitor. The arrows show in which direction the anker swings. 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.

I decided to use 12v to my paraset. The power supply is also tested september 15 1953 the power supply is very simple. The transmitter has the paraset style parallel series tuned tank circuit and seems to load well even with a random length wire antenna. With new rubberbands it s fit for fight.

This power supply is also used with other projects as a utility power supplly. A test with a 15w 230v lamp. A series dropping resistor drops the output of the supply to 250v. This one was very noisy so i opened it.

The b power supply uses the standard full wave center tapped configuration. This is the power supply i use with the paraset replica.
