    Description

    Two Hot Cathode Vacuum Gauges Varian Type 572 and Mason Renshaw 336K. Condition is "Used". Shipped with USPS Priority Mail.
    This offer includes two hot cathode gauges. Neither gage has any ion burns so I expect that they have not been used.
    Varian Type 572 has two tungsten filaments, both are good. The problem with this gauge is that one of the grid spot welds is broken. it should be fully functional with the right side of the grid connected.
    Mason Renshaw 336K - I have not heard of this manufacturer so this is probably a real antique. It's got a single ribbon type filament, which tests good on my meter. Might be a thoriated filament, I don't know. see the picture for the detail.
