“These are the best Matsushita PCC99's I have had in my PS Audio BHK pre, but they are starting to present some problems. Rushing noise in the left channel, and pulsing in the right. Both are at a fairly low level so far. Service from Upscale has been great. These tubes do sound very good in the BHK preamp, the best I have tried so far. But this is my third set of them (from different sources) and they have all been problematic in this preamp.”

“They are fine. I rolled them out for Siemens A-frames which i liked much more. These were used in a Schiit mj2 headphone amp.”
