Built a adapter to test my 300Bs on my Eico 667 tester.

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I have been wanting a way to test my 300Bs on the Eico 667, and I finally found the info to build the required adapter to do it on other forums. The info shows building a more complex one for other tubes besides the 300B, but I only intend to test the 300B, so I made it simpler.
