B&K 747 Tube Tester

The B&K 747 is a transconductance type tube tester that does a decent job of testing many of the newer tubes. Unlike the 700/707, this tester is totally solid state. This tester only checks more modern tubes and is not recommended for antique radio repair.  It is more suited for the guitar amp service man or CB/Ham service shop since it checks all of the octal and later type power tubes and is able to check double triodes like 12AX7's without any control resetting.
