STARK 12-22A Tube Tester

Here is a not so common Canadian built tube tester, The STARK 12-22A, Built in Ajax Ontario and very similar to a Hickok design and internally is like a 600A or 6000A. This one is in great shape other than a bit of the tolex on the case.  These seem to be  on the rare side and dont come up for sale very often. This one is very accurate and reads a NOS 12AX7 at 1150/1150, the 12AX7 bogey value is 1150 on the chart.  The wiring is all done very well with ferrite beads all over the place to stop any noise or oscillations.
