4 Vintage NOS Delta 12AU7A Amplifier Radio Audio Vacuum Tubes TV-7 Tested D21

Here are 4 vintage NOS Delta 12AU7A amplifier radio electron audio vacuum tubes. I took them all out of rough boxes. They tested on my TV-7 116/104, 116/106, 118/112, and 118/118 with minimum values of 56/56, so EXTREMELY strong, new testing tubes.

I purchased a LARGE collection of mostly NOS vacuum tubes which I will be listing so be sure to check my other listings.
