This is a well matched pair of Ken-Rad 6N7 metal vacuum tubes. They were made by Ken-Rad in the USA. They both have well balanced plates and are visually very similar to each other. They were manufactured to rigorous military standards so you can expect low noise and microphonics. They have a black metal case and faded white lettering. These are highly sought after Ken-Rad 6N7 tubes, act quickly before they sell out!! More available upon request.

These are listed at a nice discount because they are a little rusty. Electrically, they are excellent.

Be careful buying tubes from sellers who list tubes as matched if they do not provide test results or the equipment that they tested their tubes on.

I personally tested these tubes on my recently calibrated Hickok 600a and my TV7D/U and the results are as follows:

2,475/2,450

2,525/2,450
