The TV-7 series of military tube testers is recognized as some of the most practical and useful testers available. The D/U was the last of the TV-7 series. These are very portable, versatile, rugged and highly accurate tube testers.

NOTE: I WILL ONLY SHIPTO THE CONTINENTAL UNITED STATES.This tester was completely serviced and calibrated in Arizonaearlier this year and has only been used to test a few items since then.This unit was compared to other testers to ascertain that it is operating fullyas it was designed, and as well as other calibrated TV-7's that were available.A new, old stock(NOS) phasotron meter was installed, and it operates verysmoothly. Sockets were tensioned, 83 tube replaced, some wires relocatedfor safety, installed internal bumper spacer, adjusted line adjust, voltageswere OK, Range F adjusted, adjusted shunt phasing and adjusted gm. Anycomponents out of spec were replaced, and 3 wire grounded cord installed A copy of the work performed will be included in the sale. I no longer doenough tube testing to justify keeping this lovely example on hand, and it istime for it to go to a good home.With proper care this tester will last a very long time.I have listed about all the information I can think of regarding this lovelytester in the description. I double box and ship only after very carefulpacking, and ship FedEx insured.

I do not guarantee older electronic equipment. I have noway to know how others treat their equipment, and can't be held responsible forimproper care or handling on the other end.
