Can I use 12SN7GTA Tubes in My BHK Preamp

I have a bunch of NOS 12SN7GTA tubes and wondering if I can use them in my BHK preamp.

In one word, no… In more words, not a chance… Your preamp uses miniature twin-triode tubes called 12AU7s; the 12SN7 is an octal-base twin-triode tube… Not even close.



Thank you Jeffrey. I didn’t think so.
