Yes, the BHK preamp and amps are that good. But before you pull the trigger you need to know this. When Bascom King was designing the BHK amps and preamp, he turned to Upscale Audio to try different tube types and get the voicing just where he wanted it. Of course using vintage new old stock (NOS) tubes could not be used for production, but we have an intimate knowledge and understanding of how to take an already incredible product even better. And not by a small margin.

Upscale Audio is not just a large dealer, but the importer and distributor for PrimaLuna and Kiseki. Our buying power means that we will give you the best price, period. There is no such thing as some deal so special that you don't call us first. Do not make a move until you call Uncle Kevvy. If you have a trade-in, we need it and will give you top dollar!!

We found a very special tube made by Tungsram called a PCC88 that Bascom King likes a lot. He should. They add a level of texture and sense of space that is incredible. This upgrade alone will yield a 10% increases in performance. If you already bought a BHK product you can buy this tube from us. But there is another version that I found 20 years ago with markings from the German Post Office (German Bundepost) decades ago. Why they would need such precise tubes is a mystery, but I have seen 6922/CCa/PCC88 etc with these special markings from Telefunken, Siemens, and Tungsram maybe 5 times in my life. A Telefunken CCa from the German Post I sold for $450 each and kept the last stash for myself. And I will set aside some of these. That’s how rare these are.

To make this upgrade the best it can be, we first had them Cryogenically treated at the best lab in the country, Controlled Thermal Processing. We graded them by first selecting those that have the highest transconductance for longest life. Then we look at the measurements and accepted only the ones with the tightest triode balanceWe then tested them again, this time for gain, so the two halves of the tube amplify equally and required a 5% balance. If they pass that test, we put them in a moving coil phono stage with 60dB of gain and listen to them with headphones, carefully listening for both noise and microphony, to achieve the absolute blackest background.

This tube we are calling the Tungsram BHK Select, and is not available to the public. We can offer you the regular Tungsram, but not these. The standard Tungsram yield a 10% bump in performance. The BHK is off the hook. Remember: This is the low voltage gain device and it’s absolutely critical in determining the sound of BHK preamps and amps.  

Every BHK power amp and preamp purchased from Upscale Audio will come with TWO SETS of Tungsram BHK Select tubes Free! In addition to the stock tubes, so you will get a product with a HUGE increase in performance for many many years.
