The tubes tested similar/good on this unit and the line test feature/adjustment allows centering of needle pictured. The tubes tested similar to how they measured on multiple other units I have for sale. I am selling several vintage tube testers and tested 2 tubes across all the units for sale.
This is very good tube tester for measuring mutual conductance, gas, and shorts. The tube shown under test are not included. The two tubes I tested did register correctly when the selector switches were set as found in roll chart. The unit is heavy 25 lbs and actual shipping charges will apply.
