Hot Arcturus #26 Vacuum Tubes

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

***** Tested on our  proprietary  tester , the E3444.


It's a Triplett 3444  that has been enhanced.


This tester uses regulated power sources for the bias, plate, & screen voltages, as well as modified operating & testing procedures.


Filament voltage is also controlled. 


Tubes are tested in accordance with the manufacturer's specifications; measurements closely align with a laboratory tester built to rigorously measure vacuum tube characteristics. 


Tubes can be accurately matched for gm & plate current at the manufacturer's specified test points or at other specified test points.


***** This tester was prepared by Mr. Paul Hart of Roswell, GA  *****
