WESTON 981 Type3 Mutual Conductance Tube Tester

The Tester is in excellent working condition . I have compared Test Results to my Calibrated HICKOK 539C , and they have very close Tested Mutual Conductance numbers .

This was done on a number of Tubes including 12AX7 , 12AU7 , 12AT7 , 6DJ8/6922/7308 , 6550 , KT88 , EL34 , GZ34/5AR4 and more .All were very close I will Include a Copy of the Operating Manual along with a List of newer Tubes not listed on [ the excellent working Roll Chart ] The Metal Case is in good condition with a few paint scratches and bumps , really almost very good as I try to be conservative .

I will guarentee th the Tester will not be DOA . I can\'t do the same as to the Results compared to your Tester .

I will ship to the US FedExor International USPS. The Unit weighs about 20 pounds
