“Upscale is great and I will continue to do business with them. This tube may sound great in your preamp but caveat emptor if you are using it with the PS Audio BHK Pre! These tubes caused my PS Audio BHK Pre to whine when turned on from standby. None of the other brands I have tried including 12AU7s from Psvane, RAM Tubeworks, and 2 sets of GE 6189W (bought from Upscale) had this problem. My conclusion is that there is an idiosyncratic compatibility with this tube (or batch of tubes) the Pre does not like.”
