Precision 10-xx Prototype
Does anyone know anything about this tube tester?
I believe it is a prototype Precision 10-xx that never saw production. The meter is from a 10-12 tester. The power supply uses a top hat solid-state rectifier instead of a #80 tube. I can test tubes on this unit using the test data from a 10-12 tube tester.
The buttons for “W”, “X”, “Y”, and “Z” are individually pushed to make the connections to the tube rather than the lever switches like on the 10-12. There is a knob that is pulled to clear the pressed buttons.
There is a “Gas” pushbutton that is not connected. There must have been plans for a gas test in this tube tester. A compactron tube socket has been added.
I would appreciate any information that anyone has about this tester. Contact Me if you know anything about it.
