My Tube Collection, Welcome to share yours

Thank you for explaining things to me earlier. I went through my Philips ECC83 tonight and reorganized now that I have a better understanding. Found one other Copenhagen in there. Short plates on the right side. 
They're in the boxes of eight with elastics on them so not visible. I try to group my tubes together by construction. The short plate tubes on the right side and long plates left here. I'm too cowardly to take all them out of the boxes. I'd never get them back in order either. I don't know how you do it for some of the pictures you've taken.
Out of the Philips ECC83 I tried I like the welded plates the best .
Yes the welded plate MCA is the most expensive ECC83 at the moment , two of them was sold on eBay for £322 and £423 in the last couple weeks. I'm lucky as I have 8 of them.
The date codes I have for the welded plate are 4 mCA and 1 mCN. Also another mCN that is stamped plate copper rod 45 d getter . Rest of my Philips are all Heerlen.
Very expensive ECC83. I need some of your luck! I always love looking at your tubes and you take excellent photos. Most of my tubes are acquired with patience and planning. I'll break down occasionally and pay fair market value if I really want something.

I listened to a 10 000usd tube amp and headphone system yesterday , seriously underwhelmed, my modest 1000usd system sounds much bettter …. Maybe money is not everything, maybe it is my NOS 1944 6F8 that does the trick …
What were the components and tubes in the system you listened. What are yours?
In my opinion those are the nicest tubes you have posted out of a lot of great stuff. I’m drooling!
10 000usd in my country.
Mine is very modest a pair of 20 years olde Grado 125, and this . Custom made J.Soundlab Triode connected 6550 Svetlana Winged C and NOS Raytheon 6F8G - using a modified AppJ headphone adapter to get proper level and noise floor lower than audible. I bought the amp new for 600usd some years ago when I had 96db speaker..took it back in use just to see if it could work as headphone amp. Measurements are not very good compared to SS , but 0.1% THD is inaudible, the same is a bit drop at 20khz. No hum no noise no hiss thanks to my modification: giving a 6/1000 voltage divider to headphone and a tube load of 166ohm makes the 6550/KT88 work very linear, and still within allowed tube Voltages and current
Roon with EQ if i bother.

The earliest made Valvo 6201, not gold pins and one suspend getter support 
I do not have so many rare tubes as others, but I will share one which I think it was not presented here until now, the Siemens E288CC (branded Telefunken).
Boxes are standard yellow/blue Siemens ones. A detailed photo of the tube:
I am not an expert on date codes, but I guess N=E288CC, 5th revision, 8 might be 1968 and L is December.

I will continue in the same area of Siemens frame grid tubes. Here we have from left to right: Siemens E88CC Aϕ, Siemens E88CC A4, Siemens E88CC A6 (single stage getter), Siemens E188CC Gϕ (on base, A2 inside glass), Siemens E288CC N5.
Here some detailed photo where the date codes inside the glass are visible.
I am intrigued why on the E188CC I have A2/7B inside the glass but Gϕ printed on the base. A detail of the base below.
The tube seems to be manufactured in Munich by Siemens-Halske. 7D seems April while the date code inside the glass is February of the same year, so we might have a date code applied on the base at a later point in time than the one inside the glass. Constructionwise, seems an E188CC.
What to say, one day I will understand more about these small and very nice tubes.
