The Amperex '65s OGs. How different would the 67's be? I only asked becuase I've got a couple pairs on their way.

I own a bunch of Philips valves.
USN-CEP's are 1965 (6922)
I have 2 sets of OG's
69' dimple getters
67' small "O" getters (yours)
I also have 1960 "D" getters and 
My1965 La Radiotechniques.  Are Big "O" getter, gold pin E188CC's and were made in the Philips plant in Heerlen Holland, not France.
Another set of E188CC gold pins are on the way.  They are "RTC" labeled but made by Mullard in the UK.
 
The 67's are very good.  But I also enjoy the 69's
You will be pleased.
 
There are a couple build differences over the years.
Later in the sixties the design went to  "Dimple" getters.  (A disc with bumps) and an "A" frame rather than a single post.
But there are exceptions.  My 67' and 69' are a single post.
 
If you'd like to learn more about valves here is a link to a Dropbox with some good documents.

EDIT:  I have some valves not made by Philips from the 70's   Something changed they just don't have the musicality of late 50's to mid 60's
Hence, I stick with the 60's

Anyone know any UK sites that sell lots of tubes? ebay looks a bit sparce apart from foreign sellers.
 
Seems like all the good old british Mullard tubes have grown legs and walked abroad, can't seem to find any in this country

Does it matter that they're not matched? I've been looking for matched pairs but no idea if it's absolutely necessary.

Retraction:
The information in this post is inaccurate as the listing on eBay was incorrect.  The tubes/valves in the eBay listing are from the 70's / 80's.   The eBay vendor has been notified  I believe I made a post with similar information.  I hope that this has not had any adverse effects..
 
Matched is a very good idea....
I took it on faith as they have a large quantity of these valves and they are a regular valve seller.
They should know to match.
One of the other members posted that they were a reputable seller.
 
They goods look perfect.
 
The E188CC is a very good valve.  I have a set made in Heerlen Holland that I love so much, I wanted a backup pair.
I think these are a fair price for 1960 vintage.
 
The ad states a "R0D1"
R = Mitcham UK plant, "0" is 1960 "D" is April "1" is the first week
 
VR1 is the valve type.  E188CC
 
 
BTW.  You don't need "balanced" with a Lyr.

The question is frequently asked here "How long do tubes last?"
 
In reading tube/valve specifications for the Telefunken E88CC / 6922 / CCa
it specifically states:  "We guarantee 10,000 hours of operation, averaged over 100 tubes.
 
At the bottom of the sheet it specifies compliance with USN MIL Spec  This valve type is known for reliability and tight tolerances.
So there it is, straight from Telefunken.
It's a multipage doc.  I only attached page 1

Since you have them too, what's your take vs. the other tubes in you library? I like these about as much as I like my two sets of JAN Amperex ('65 JAN-CEP 6922 and '66 JAN-CEP 7308) but the sound stage and treble isn't as good as my Telefunken ECC88s (then again, the bass is a little better on these). Haven't had time to compare against the Brimars though.

Ok, so admittedly with only a few hours of listening, I have some thoughts.  These Lorenz SEL's are pretty sweet. I think the bass is more controlled, slightly deeper (I think?) and consistant across the range than with the Matsu****a's. The mids seem a bit more present. Instrument separation seems better with more body and sense of space to each instrument. There seems to be a tad more sparkle (I was going to say sizzle, but I dont want to give the wrong impression) to the top end for good and bad.  Seems to add a clarity to the sound. Soundstage seems about the same, though the music seems a bit more open and airy.  
I think they are keepers

  Thanks to whoever first pointed these out the other week.... Sorry I can't remember at this point. Hopefully you know who you are.
 
Maybe I'll give an update after a few weeks....
