Parts Unit - B&K DYNA - JET MODEL 747 DYNAMIC MUTUAL CONDUCTANCE VACUUM TUBE TESTER




Item History & Price

Information:
Reference Number: Avaluer:64584980Brand: B&K
Original Description:
B&K DYNA-JET MODEL 747 DYNAMIC MUTUAL CONDUCTANCE VACUUM TUBE TESTER. This tester powers up and lights tubes. It developed an issue where it was reading low on known good tubes after i tried using it after some years, i tried the calibration procedure, and it wouldn’t calibrate, so i changed the electrolytics and still not reading good or responding predictably to the calibration steps.
Has no missing parts and the setup book is all there but the binding is in poor conditio...n. The cosmetics are indicative of need for cleaning but latches and hinges intact.
Thanks!
