    Designed for use in Type 530, 540 and 550 Series Oscilloscopes
    Used with Type 547, the alternate switching circuit can be slaved to the display switching circuit in the oscilloscope, thus locking Channel 1 to Time Base A and Channel 2 to Time Base B. This approaches the equivalent of a Dual-Beam Oscilloscope.
    ==============================================
    This is a 50 MHz two channel amp that is literally teeming with Silicon and Germanium. Closer inspection reveals six Nuvistors.
