  I appreciate all of your insight Kolkoo! I'm not too obsessed about the testing results being 100% at this point, though that would be awesome. As long as the tube has no noise, like he stated on his listing I'd be a happy guy.
 
I Kind of want to send you the tube for testing just to see what the tube really tests at.

Man if I wasn't in Europe I'd gladly offer to test everyone's tubes on here for free haha, but the postage risk makes it totally not worth it

Calling out the tube wizards.
So just bought these Amperex tubes from eBay and I'm not sure if these are authentic Orange Globes?
The seller wasn't sure which model these are so any help appreciated

From the look of it, they are sweet sounding Amperex A-Frame 70's era. You need to read the codes for the exact date.

Jawsome haha. Will be sure to do that once they arrive. So excited!

I can even see the codes being GAE delta0XX on both so they are exactly 1970 I believe.

Where is the best place to get '60s Nos Telefunken Ulm E188CC. I want a matched pair, and I've seen ebay selling a pair for ~630 but im kinda sketch on ebay now with my limited tube knowledge.

 

[TK16]

Nowhere right now TBH, I got a pair for $300 and the pair I have left for $265. Thats around the max I would pay. The market really dried up on them.

 

[Bleether]

Looks like I'm late to the party, but I guess i'll have to pay the price of admission. I doubt I will ever see those prices.

Re siemens cca tubes

Am i right to be under the impression that those with 6 numbers/codes stamped on the metal getter support (eg A0/ #1/5k) was tubes frm the 60's and those with only 4 numbers/letterz where from the 70's?

Would i have read something somewhere (very vague recollection) that 62 and 64 were good years?

And when were the codes etched into the glass? Late 50's or per haps very early 60's?

And are these legit and/or when wouod these have been around as i noticed some of these on ebay at cheaper prices



Any info is much appreciated
Peter

Silver plate were produced from 65 onward.  Look for the gray plates for pre 1965.

Thanks. Did not know that about the silver plates.

On brent jessee website it says about a siemens tube with a code of A0/1#/5G:

"Here is an example of a Siemens tube with the metal tag factory and date code. These mostly came into use after 1968.

The Siemens tag codes followed the same convention as the codes on the glass, in three lines of two characters each. This one is 1975, July, and not 1965 as the tags were not yet in use in 1965."

Correct??????

Edit: input later in this thread has held this as true - tags from late 1965

I believe mid 1965 was the change from gray to silver plates.  By 1975 as I recall they were using A frame getters.
 
If I am correct that would make these late 1965.
 
If I am not, others please chime in...
