PS Audio BHK lacking..

Hi fertguy

If you try some high quality nos tubes in the BHK Signature preamp it will transform that preamp into a very good sounding preamp. Either a 12 volt 12au7 from either Telefunken, Mullard, Amperex or Siemens from the 50’s or the 60’s should sound great. If you change the two jumpers to the 6 volt settings and the 5 milliamperes bias settings then either a pair of 6922’s, 7308’s or 7dj8’s will sound great as well. BHK’s favorite tubes are the Tungsram 7dj8’s from the 60’s. Any of these nos older tubes will elevate that preamp to a whole new level. Best of luck.

Thanks for all the choices, I will see what I can find & do just that.

For the price you played you shouldn't  have problems with the tubes sound.

if $10k worth of gear cant beat < $1k step #1 is to measure and baseline that it is working even remotely properly.  Both performance and settings (eg..; Bias)

The day I bought the BHK here on the Gon I ordered a new set of stock tubes from PS Audio.  They showed up a little while ago. I have them in now & they made a big big difference. It's starting to happen. I'm looking forward to trying some of the tubes you guys mentioned.
