The last two weeks I have been busy assembling the Tetrode Boards. They have been designed by Ian, G3SEK and they provide a lot of functions to the amplifier that makes the whole construction a lot easier! On the two boards there are supplies and regulators for screen grid and bias, HV fault and tube protection circuits, ALC, and TX/RX sequencing.
These are the assembled Tetrode Boards.
They are 5x4 inch and you can buy them either as empty boards and provide components by your self. Or you can buy them as a kit and solder everything together. You can red more about them on Ian's web page: http://www.ifwtech.co.uk/g3sek/. Ian also sells a Triode board.
Next step is to fit the boards together with transformers and the HV board into the PS compartment. More pictures will come in about a week!
