TUBES 6922 pinched waist

OK, here is what I suggest. While it applies generally, it is particularly true f rthe tubes you reference. Buy only from a relaible dealer of tubes whom you know trust and/or who will trust you to return them if needed. These can be just fabulous sounding tubes from my experience but can be microphonic to an extreme. I had a couple the sounded fantastic in Kora Eclipse that I had, but I had another pair that looked identical but rather sucked. At the price thse command, you want to be sure you can return them.

That's good advice from 4yanx. An option to the pinched waist are white label Amperex 6922 PQ made in the USA during the 60's.

Thanks Are the 7308 PQs any better sounding then the 6922 PQs

My experience with the 7308 and 6922 tells me the answer is no.

Here's a link with one man's comprehensive viewpoint.

The 6922 PQ's that Tvad references are top-flight, IMHO
