Pulled the trigger on a new BHK preamp. Expecting delivery on Friday. Waiting in anticipation.
You wonât be sorry! Only recommendation is to use 12V tubes that are well matched to minimize noise during volume change and as the tubes age.
Next set for me are newly manufactured Telefunkens
Congrats!! Let us know what you think when you bring her in. Donât forget to give some good break-in time. 100 hours will be a good start but youâll probably need more.
Have fun- not selling mine. Check the tube rolling topic
I intend to. After all having fun is whatâs itâs all about. Need a mini lifetime to go through the tube rolling topic 
Thanks @jamesh. Shall do.
Thanks for the recommendation.
Unfamiliar with newly manufactured Telefunken tubes. Did not see them at Upscale.
I would still go with NOS tubes. The newly manufactured tubes just donât sound as good as the old ones. You donât need to spend big bucks. Iâm listening to these right now and they cost $15 each. Philips JAN 5814âs.

I have no experience with the performance of new Telefunkens, but they are made by JJ.
Thatâs not a bad thing but Iâd be surprised if they sound like the NOS versions.
From the Telefunken website. Didnât realize they are manufactured by JJ (did see of Russian origin, I think).
Have tried:
NOS Amperex 7308: Great sound, but got noisy too early in their life
NOS Cifte 12AU7: Really great sound and have lasted > 1k hours so far (currently installed), but pricey.
Wanted to try something new (non-NOS) in the âupper endâ of the price range. NOS Teleâs get stupid expensive.
Thanks for the tube lead. A detailed, low noise, âaffordableâ alternative to the
stock psvanes is where I am headed as well. I am a tube novice and appreciate
the input. Might try the NOS Ciftes but canât see a source. Keep us in the loop
on how the new Telefunkens sound.
Upscale Audio did have the Cifte 12AU7âs, but didnât have the cryoâed version and were kind of slow replying back so will try the new Teleâs. The Citfeâs are pretty steep at around $350 for a well matched pair with cryo. They do sound great, but hoping something new will be close and more readily available without the inevitable price increases as the NOS stuff becomes rarer.
These tubes are fantastic. If you donât try them, youâre a goof. ThereâIâve said it.
Now thatâs a recommendation I can get behind. 
I agree- running them in BHK 300s
Running them in the BHK 250.
Thatâs awfully strong language.
