This is the power supply I use with the paraset replica . This power supply is also used with other projects as a utility power supplly . It is built on a small bread pan I use these to sort small parts and decided it would make a nice chassis for a power supply . the circuit is shown in the video . note there is a full wave bridge rectifier module and transistor filter (Hum Bucker ) used to provide filtered DC to the Paraset filaments to remove hum from the regenerative receiver . There is no filter choke for the B + this was replaced by a 200 ohm 20 watt resistor a 10 watt resistor would probably work fine but what I had was a 20 watt. This supply has a B+ voltage of 420 volts which drops to around 400 during transmit .
The filter capacitors are much bigger capacity than required they were used because that is what I had . Capacitors around 40 uf at 450 volts would work fine . A schematic is shown in the video to help anyone building a power supply like this one .
