LINKS AT AUCTION INFORMATION CONTACT updated 8/10/2017

An excellent mutual conductance tester for tubes of the 40's - 70's types. Great for audiophiles and guitar amp servicing. It will not test the early pre-octal types (old large pin tubes from the 20s & early 30s. It will test nearly all types of tubes from the mid 1930s - 1970s including compactrons etc. The B&K mutual conductance test is the same basic platform as used in Hickok tube testers.
