“These are relatively inexpensive tubes so wasn't really expecting much. They are outstanding in my MC75 McIntosh monoblocks. Detailed and focused without being edgy. Great airy and 3D presentation. Couldn't be happier. A great find! With Upscale Audio including 72 hour burn in these were very good right out of the box and have continued to improve.”

“Shipping was quick. Tube works, no noise or other issues detectable to my ears. Have not had a chance to test the tube yet to check it's numbers.”

“These are vintage Mullard. Liquid midrange, deep bass, silky highs. They are a bargain compared to their higher gain sibling (12ax7/CV4004). These military versions are extremely quiet! My favorite tubes!”

“I picked up a couple of these to replace the stock tubes in my Manley Jumbo Shrimp. I was not expecting such a night and day difference. The mids opened up into a silky smooth velvety sound that I didn’t think my equipment was capable of. The bass is deeper and more pronounced. It is almost like hearing my records for the first time again. If you have a Jumbo Shrimp, I can’t more highly recommend these. Truly incredible difference.”
