If the anode voltage is very high then stack some thyristors and fire them with opto couplers. So w; /archives//html/Amps/2012-02/msg00337.html (6,545 bytes)

It is a pulsed amplifier, so we need all the current we can get, during each mS long pulse. There; /archives//html/Amps/2012-02/msg00344.html (8,483 bytes)
