What are the best drop in subs for a 12AU7??

I am considering a Minimax preamp, but understand that they sound best with rolled 12AU7s. I have some Mullards which I would try first but have heard that there are even better choices of slightly different tubes. What are they and are they difficult to find? Thanks any help is appreciated.

Amperex 7316 and Telefunken ECC802S are the top 12AU7 tubes you can find.

RCA Cleartops from the '50s work for me. Andy at VTS has an excellent slection of them. Very low noise.

I also just acquired a pair of Amperex Bugle Boys and am looking forward to hearing the comparison to the RCA.

I agree with S23chang. RCA 5814's and 6189 COMMAND versions should also be considered if you can find them.
