- Hi, All ! Check the DL2KQ web site. There is a lot of info about the compact power amplifiers with transformerless power supply. He uses a 220-240V mains with 4x rectifier-multiplier. The isolation i

- Hi, All ! What do you think about switching HV off with the vacuum relay ? Is it better than fuses/circuit breakers in the primaries of the PS transformer ? All the best ! Oleg 73 de UR3IQO _________

- OK. Consider I have a 40 uF capacitor in the PS charged to 3000V (one that uses in the pulse laser PS). Will it be safe for electronic crowbar to discharge it ? My idea was having a glitch resistor a

- Hi, All ! I am going to build an amplifier using GU-46 tube. It is glass pentode. You know in the tetrodes we need to use a shunt regulator to cure the negative screen current problem. But is it safe
