SECO Model 78 Tube Tester. Serial No. 4475. Late 50\'s early 60\'s?

Picked this up at my neighbors garage sale. He used it for many years.. I have used on and off for 4 years. He had found it at an estate sale.. the plywood case was ruined by dampness. It has been taped and painted.

This instrument works. In photos 2 and 3 you can see tube 6K6 being tested. In photos 4, 5, and 6 you can see tube 12BA6 being tested. Flip up tube guide is clear and complete. I have included a copy oftheinstructions along with a copy of the tube guide.

If your looking for a pristine collectablefor display.. this tester is not for you, but if you want a working tester for your bench.. don\'t miss this one! ( of course you could always build a new case!).

Thanks for looking! RWF
