Amperex PQ 6922 vs Amperex PQ 7308


I've read the Joe's Tube Lore re: 6922.There was NO mention of PQ 7308.Will these still be the same performers,or is one superior to the other.Thanks!!

I hope that I didn't step on any toes by diving into this thread. I was just relaying what I've learned from Andy @ Vintage Tube Services and what I've learned in 6yrs of trial and error with small signal tubes. Ed- I read your review of the Shuguang/Super TNT 845B tube. It looks like you've been around tubes for a long time... as I said, I hope that I didn't step on any toes. Best! Stan
So,I ask,once again,which would you guys prefer in a phonostage.The PQ 7308 or the PQ 6922!!Thanks.

Also,since so many of you are quite knowledgeable,do you think I'm wasting my time,since I already own very low noise Ediswan 5358's that I'm using in my phonostage?Or,should I still be persuing a good set of PQ's?
I think that either the 7308 or the 6922 PQ would smoke the Ediswan tube. The 7308 would probably have more longevity and be a quieter tube than the 6922. I tried to Email this to you but I got server error messages. If you want a reccomendation of a good place to buy tubes, click on my system for my Email.
Best! Stan
Gotta agree with Talon4 and disagree with Dekay. There is a difference b/t the PQ and JAN versions. I prefer the PQ
Talon:

In general the Holland 6922's and 7308's are a bit softer sounding than their USA counterparts.

I usually prefer softer sounding 6922 types, but I ended up keeping only USA versions for personal use (so there are other subtle differences which I am unable to describe well).

I've read that PQ's were screened for close section match, but as mentioned I've never detected a difference between the PQ/Non-PQ versions I've gone through. I have both types sharing the same production/date codes (they are the same tubes).

JAN/USN, etc., were marked such for military purchase orders (same as tubes being marked IBM for IBM PO's, Fisher by Mullard, Telefunken tubes marked Pilot Radio Corp., etc.).

In all the gear I've used White label 6922's have fuller bass/mid-bass than White label 7308's. The 7308's have greater HF extension than the 6922. My preference is dependent upon the system they are being used in.

Never tried 7308's in a phono section.
