6922 recommendations for ARC PH7
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. |
6n23p Voskhods Rocket logo, 1974-1979 period, earlier the better, you will not look back for other NOS, and are more economic than western alternatives. Fit and forget, simply they are not sounding like hifi and have a better musical flow, and are quiet. Prices have gone up but they worth it, only thing to find a is a good vendor. |
op for the ’improvement’ you seek i would suggest 3 old stock options -- ecc88 or pcc88 from tungsram (hungarian production) - expensive but not crazy expensive -- 6dj8 or ecc88 from telefunken, valvo or mazda (france) - crazy expensive not quite as good but very close -- ei (ram logo, yellow lettering) ecc88 from old yugo plant - still reasonable |
Hi Keith, I use an ARC PH3 SE. These are the best but you will not like the price https://upscaleaudio.com/collections/preamp-tubes/products/telefunken-cca 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. I may try these, https://upscaleaudio.com/collections/preamp-tubes/products/siemens-a-frame-e88cc-6922?variant=295304... Fortunately, my unit uses only three tubes. The "Kevin's Stash" grade is $160 per. I continue to argue with myself. I really think you will be very pleased with the E-H Gold/ |
