12au7

My 12AU7s and 12AX7s are all ribbed-plate Telefunkens from Andy at Vintage Tube Services. In my opionion, for the most linear sound top to bottom, they are the best. Jason

HI KILLERPIGLET,
Yugoslav El 12ax7's,that's what i have in my paragon 12 preamp now,they are new, maybe they have to break-in??? based on the Telefunken design maybe,sound i dont think so.

I have about 40 Baldwin 12au7 tubes I recovered from an old organ. I wanted the 5u4s and could not stand to let the rest go to waste. They are made in the USA, have green type and test very strong. If any of you would like to give them a try e-mail your address and how many you want. And Please let me know your opinions.

How about Amperex Bugle Boy 7316?... about to try out a pair myself here in a few days. I'll report back..

I'll have to agree with Jason. Of course, I don't think Telefunken made a bad tube. They're definitely the cat's meow when it comes to the AU and AT.
