What age do you guys think these are from?

In the description they guesstimate that they are 60s but a confirmation would be great. If they are I might grab them as Miniwatts seem to have the warm smooth trebled sound I am looking for, similar to Mullard and Voskhod tubes. Thanks again to everyone that has helped me on my tube quest so far!

 


I would recommend holding out for E88CC or preferably E188CC Philips Miniwatt or Valvo, making sure they are from the Heerlen factory (delta code), 1965 or earlier. That "dimpled getter" and the 1969 date would scare me. If you keep your eyes opened you can often get the E88CC's for $75-$100 and even get the E188CC's (my favorites) for under $100...certainly under $150. It's worth it. Just make sure you check out the date and origin codes and test results. Also ask if there is any tube noise (hum, hiss). If the seller isn't forthcoming, stay away.
Good luck.

  What I find interesting are the two(?) posts, one of which seems to support a dimpled "getter" and possibly something above it (an 'O' "getter"?).  Any ideas or comments?
 

 
I checked one of my GACs but they are all 1968 and still have ring getters. I suspect we are seeing the stub that could have supported the ring getter but instead had a dimple disc getter with its own support attached to said stub.

Seems to be every time I find something that might be good someone recommends something even more expensive 

 My max price would be £100 so around $150 so those tubes you recommended viable but if I am spending that much I want to know I am going to get the absolute best performance I can for the money. My main problem seems to be within Europe I cant actually find any of these decent tubes people recommend.
 
Just to reiterate I want a nice deep warm bass with smooth but detailed treble and its going to be with a Bifrost Uber and Hifiman HE-400i.

Regarding the extra posts that seems as good a reason as any I can think of, I am a self proclaimed tube noob (although I am trying to learn) so you would have a much better idea than I would.

Can't guarantee a thing...always comes back to bite me. I've bought from this seller (in Europe) and have never gotten screwed. I'll bet you could end up getting these under $100. Check it out:

They appear to be from a German factory according to the seller. Does that really make much of a difference compared to the Holland factory?
 
What about these ones? http://www.ebay.co.uk/itm/MATCHED-PAIR-E88CC-PHILIPS-S-Q-Audiophile-Double-Triode-Tubes-CCa-6922-CV2492-/311177657255?pt=LH_DefaultDomain_0&hash=item4873a23ba7

 

[billerb1]

He always says the Valvos are made in Germany...but the pictures and his description both show the delta (triangle) code designating Heerlen.
Ask for verification.
The other Philips have different version codes, which I tend to stay away from...although I've had some great pairs that are mixed.
Like I said, never any guarantees. You can do all your homework and they still aren't quite the sound you want. It's a tough world out there.

I see the 'R' factory code on one of those tubes.  That'd be the Mitcham plant, which seems odd for that tube type.  Also, look at the getter posts: definitely different.

 

[Rowethren]

Yeah I can see looking at them that the posts are different, one has notches in it and the other is straight. Dare I ask again (sorry for spamming the thread) but I cant seem to see anything wrong with these ones so what do you guys think?

I'm not sure 7LH  translates to 1964.  Hopefully someone who knows those change codes better will chime in.  If 1964, I'd say that's an excellent deal.
 
Found this old post, which is the one I was thinking of.  You can read the whole exchange starting on that, or the previous, page.

I don't consider legitimate questions about potential purchases spamming.  Quite the opposite.  I'm always encouraging people in PMs to ask herein.  So, as far as I'm concerned, keep 'em comin'!

I am in the same boat, I am only just starting to understand parts of the code. Thanks for the link I will give it a read now.

I'm afraid H makes them 74.

I gave you props in an edit

I knew it was too good to be true 

 thanks for the date clarification. Well back to the search!

Saw that, subsequently.

I was concerned about the H as well. I agree with Oskari.
