This is a Dynalyzer II. We now manufacture the Dynalyzer IV. It is used to measure the output of X-ray generators. The large board is called the receiver board. The smaller one is the oscillator board as it provides drive to the isolation transformer inside the tank. The max voltage for either side of the tank is +80kV anode and -80kV cathode.
thank you, it says Dynalyzer III on the board, though. I did not know there was an isolation transformer. I wondered how that worked. Would you happen to know the max current it can handle? (From transformer anode to tube anode, or transformer cathode to tube cathode)
