<<<Sold>>>
Selling a NOS pair(2) of 12SN7 Tungsol black glass round plate tubes. These are the 12v heater version of the famous 6SN7 TSRP.
I have owned these for a several years but they have not been used. I do not have the original specs but I always buy either NOS or else used, but test as new. If you test them within two weeks and they do not test as new you can return them to me.
Note: These
must be in a circuit that provides 12v to their heaters. These are perfect in a Linear Tube Audio preamp or headamp with the 12v jumper.
Asking $175 shipped to 48 US. Pay Pal or Zelle.
Best,
Paul
