Waaaaaaaaaay better than most 6922 variants.

Good to know.

I have some of these tubes for my Yarland P100 amp. Hence, I just need to but a pair of adapters and then use two of these 5670 Tubes in my Valhalla 2. Please let me know if my idea is wrong.

At $15 per pair with shipping, I may take a chance on these as well.

Do they need to be matched? They only seem to sell singles.

For those that know about the WE 396A, what is the difference between the JW WE396A and WE396A? What does the “JW” signify?

 

[wwmhf]

If I remember correctly, J means for military usage, W means extended life ...

 

[wwmhf]

These are what I found, and I hope they work on Valhalla 2:

J for JAN meaning Joint Army/Navy and W for Western Electric. Military version of the 396a.

 

[Wes S]

Thanks for the explanation! Is there a difference in sound between the “JW” and the regular WE396A?

 

[Guidostrunk]

Some say they here heard a difference. I never have.

Awesome! Thanks! So probably like the Amperex PQ and USN-CEP? Both are the same tube, one military and the other consumer.

The 5670 adapters have now shipped, and quite quickly too, from Hong Kong. Unfortunately, the attempt to track the package was convoluted, yielded no results, and even put a virus on my computer which, happily, was picked up by Bitdefender. I imagine they'll get here, but not in the three days it took for DHL to deliver a Little Dot amp from China to NJ. I guess I'm a little gun shy since my only other Ebay purchase from a non-US seller (a pair of tubes from a Latvian seller) shipped quickly, but the tracking information never indicated the shipper or updated beyond "shipped" in three weeks. To his credit, the seller did issue me a prompt refund when I complained.

Does anyone know if those adapters negatively affect SQ? I know some people reported some socket savers that did.

I don't think so, at least for the 5670 adapters.
