Tube recommendations for AES AE-3 Preamp

Though they will not equal the likes of Sylvanias, I have two recommendations for low cost tubes.

Raytheon and the silver colored metal based Shuguang 6N8P. Both sound satisfyingly good, at pricing that comes in lower than the lousy sounding current production out of Russia and China.

I have an AES AE-3 Mkii preamp and after some tube rolling I settled in on vintage yellow writing Sylvania's.
The vintage Tungsols had a bit less of a soundstage as did the RCA's.
The new production EH's were my least favorite.
Also, I replaced the stock GZ34 rectifier with a vintage, early 60's Mullard GZ34.
It mates up well with my AES Superamp Mkii as well as my just completed Bob Latino M125's.
I love the sound of this little preamp and the remote is a convenient feature.

Thanks for everyone's input. I found a good deal and settled on some matching NOS Sylvania GTB black plate chrome domes....

Anyone have any experience with these tubes?

Make sure they are quiet. Many of the preamp tubes for sale in cyberspace are noisy.

Hmmm...I would certainly hope they're quiet, but like I said I'm new to tube components so I may not recognize abnormal levels of noise caused by defective tubes. Any thing in particular I should look out for
