Honestly. It sounds like the 55 you sent me. The 55 and 52 are a little more balanced than the 59. The 59 has a little treble tilt.

I sent emails out to a few people on the Asylum to get more information on the 52. The code is confusing because of the welded plates. Copenhagen looking triangle , but supposedly they never made welded plates on ecc81. Only the ecc82 & 83.
Either way, the tube sounds phenomenal! Lol.

How does that possible Copenhagen sound like? A more refined mid 50's ECC81 Heerlen. Not as warm?
Putting in my pair tomorrow for more burn in time.

Think it was a 58 I sent you, this 53 Copenhagen does not have welded plates, same as my 2 pair of 51 Copeys.

My bad. A 58 and a 55. I think lol.

That's the thing also. I've been searching images of early Copenhagens. I can't find one with welded plates. Even sold listings on ebay. Also , all the Copenhagen tubes I found. None of the triangles were turned in a weird position on the codes.

Yep. Got it in the sniper list. Lol. 1953 welded plate.

Edit: I think it's Heerlen. Kolkoo wasn't sure if the 52 I have is Heerlen or Eindhoven. From what I've read on a few other sites. Heerlen only made the welded plates for ecc81 variants. Crimped plates for ecc82 and ecc83. Only person I know who would have a definitive answer would be @Oskari

That date code looks like a possible 4 rather than a crooked delta.

The second Philips Monza ecc81 (1Z 8G) arrived so I finally got to try the pair out. They sound promising so far, maybe a bit veiled in the upper mids, but I'll see how they are after a good 50 hours.

I've also been trying out the Valvo early 50s coin bottom for the last few days - one ended up noisy, so dropped in a spare. Very impressed with these. On the same level as the 6201, but with a bit more harmonic distortion.

Italian tubes represent! I enjoy these Monzas (the D-Getter ones from 1955 as well as the O-Getters from 1960 that I have).

I just finally was able to assemble two singles of Marconi Italia ECC81 early 50s D-Getter. Unfortuinately one of them has copper rods and the other one has metal/silver/nickel well white-looking rods.
I've just popped them in at work for a listen - no noise on high gain in my Lyr2 so they must test decently. I am enjoying them so far but I need to listen to more stuff.

Also I'm 99% sure the welded plates are Eindhovens or Heerlens.
