What ecc82 for preamp

Telefunken Smooth plates, Brimar Square Getter long plates, NOS Tesla ECC802S ( not JJ ), Tung Sol Black coated glass.

Personally, I love Mullards made between 1950-60's, but you may find them to warm?, however thats not the case for my taste.

There are many variations of ECC82 you can choose from: 12AU7, ECC82, ECC802S, CV4003, 5814A, 7316 and M8136

Good luck

This is a problematic tube because of high distortion.
I have had better results with 7316,5814A,E80CC-if the additional heater current needs can be safely met,and Telefunken ECC802S.

Here is another site with an opinion about how they sound.

The ONLY problem with Telefunken ECC802S is they go for $850+ for a MP and almost impossible to find a MQ.

Thanks for the leads and input I think that I can find some nice tubes based on your help certainly better than new production tubes. Way to go my audio bro.
