Paraset Power Supply

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

Paraset power supply.

A test with a 15w 230v lamp. The power supply delivers 6 vac and 350vdc. The arrows show in which direction the anker swings. The rubber bands who kept the chassie in the holder had vanished.

The b power supply uses the standard full wave center tapped configuration. For other radios separate forums can be set up ask the quartermaster. One of my ham radio buddies calls this the paraset mini cooper. The power supply is very compact in a great box.

A 5y3 gt or a pair of 1n1007 silicon diodes if desired is used as the full wave rectifier. This power supply is also used with other projects as a utility power supplly. Consisting of transformer rectifier tube 6x5gt and a capacitor. 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. With new rubberbands it s fit for fight. It s not easy to find vibrators today. The transmitter has the paraset style parallel series tuned tank circuit and seems to load well even with a random length wire antenna.

The output is smoothed by a pair of filter capacitors and a filter choke. This is the power supply i use with the paraset replica. I decided to use 12v to my paraset. A series dropping resistor drops the output of the supply to 250v.

This one was very noisy so i opened it. The voltage parameters measured on the receiver section are shown below.
