Upscale sells tubes of the highest quality. My go to sellers are Brent Jessee and Andy at Vintage Tube Services. They sell high grade tubes and offer a return policy, which is great for a tube roller such as myself.
6922 recommendations for ARC PH7
Hi folks,
Looking to roll the tubes in my Audio Research PH7 phono pre. Looking for a recommendation for a 6299 that will extend the top end, midrange and give me a little more airiness without sacrificing the bottom end (Sorta what we are all looking for right lol)
the tubes I’m currently using are 4 Electro-Harmonix which sound good but they are a little laid back on the top. Very neutral sound which is a good thing, but want to try something new. My main room is not a very lively room as it is. However after testing the ARC in my living room system which is much more lively room I still am not getting the result I’m after. Dont get me wrong. Not complaining about the sound of the pre at all. I have been wanting to roll the tubes in this piece for some time now if not more than to just experiment with. Just got the itch to try something new.
Thanks

I've used the 6922 Phillips SQ and the premium 7308's. They have outstanding sonics; a liquid midrange, smooth extension at top, with a huge soundstage. The 7308's have deeper bass. I've rolled so many 6922 variants that I feel the Philips are really special. It's the same tube as the Amperex SQ. Also Telefunken, but they're pricey. |
These are much more reasonable https://upscaleaudio.com/collections/preamp-tubes/products/electro-harmonix-6922-gold-pin?variant=29...They are the gold pin Electro-Harmonix. I have the "Kevin’s Stash" grade and they have a very clean top end and are also extremely quiet. Sorry, but I’ll have to disagree about these tubes. I recently bought a pair and the highs don’t hold up when pushed. My pair sounded artificial at the top-end, not realistic or natural. However, they were full bodied and very quiet. As always, YMMV. |
Amperex tubes manufactured in the Heerlen plant were not all the same. The PQ series were different than the Bugle Boys as were the rare pinched waist tubes. From Brent Jessee: E88CC / 6922 Amperex Holland made white PQ type, white label gold pins. Holland tubes marked with the Bugle Boy logo were 6DJ8 type, no gold pins. Later 6DJ8 production tubes with white or orange labels were the same tooling as the Bugle Boy. Bugle Boys from Holland were the same tube as the Philips Mini Watt. An Amperex PQ 6DJ8, 6922, 7308 were the same tube measured to the same tolerances as a Philips SQ. |
