50.187.28.33
I was perusing EBay and I came across some GE 12AX7s ECC83s a sleeve of 5 very nice and neat. I thought that these were not made by GE immediately for some odd reason. When the tubes were examined, I saw as bold as you could print it on a tube, "Made in Poland". I have never heard a polish tube or anything about them. GE printed the 188-5 EIA code on them to confuse matters because that would mean they were made here. So has anyone heard a Polish tube or can tell me about Polish made tubes?

Polam made very good EL34's. I've got a bunch of NOS and the internals are exactly the same as the old Teslas. Maybe a case of rebrand..or using same parts and manu in Poland. Irregardless...they are really nice tubes!

I use POLAM PCL86 tubes in a SEUL amplifier.
Seriously GOOD tubes, made with Phillips tooling (I think).

If my memory serves me, Polam also made an EL34. It has a pointy top like a 9 pin tube. They are somewhat rare but are great sounding tubes. cheers, Dak
This is copy pasted from the web (link below)
1. There was a big factory in Warsaw, called "Zaklady Wytworcze Lamp
Elektronowych".
Tubes were marked with ZWLE, Telam, Polam and Polamp brands.
See http://www.mif.pg.gda.pl/homepages/frank/brand.html for logo.
ZWLE produced mercury discharge and fluorescent tubes also, and bancrupted
in early 90's.
2. Second (smaller) factory - "Dolam" was located in Wroclaw, and produced
tubes in smaller lots - octal tubes, some soviet types (but marked in latin
letters !). Dolam was also producer of Nixie displays.
See http://www.unitra-dolam.pl/index_en.htm for their contemporary product
profile.
3. Third producer - "Lamina" - located in Piaseczno, produced tubes for
military/industry/broadcasting use (e.g. latin marked GU-50).
Lamina still exists: http://www.lamina.com.pl/Lamina/myweb7/products.htm
Some of Polish tubes were also marked with Unitra (trade company) logo.

A Polish electronics manufacturer may have bought them from GE and printed their own lettering on them.
Are there any acid etched marks on the tubes?
Polam, Telam and Dolam Polish manufacturers made excellent tubes. In the same league as Tungsram.
If you can post a picture, it would help.
TM, I have some of these. I presume they are Tungsram made. Due to stamped number on foil on anode plate?
Thanks!
EL84 in your picture is proper Polam, Polish made.
Plates and bottle are typical Polam. Tungsram plates are very different.
Numbered chad is also common in some polish tubes but not always.
Guitar folks love these Polish EL84's.
Thanks! Didn't have a chance to compare with my Tungsram stash. I haven't tried these Telam tubes. Maybe, this weekend in my Matchless.

Thank you all for your responses. I had forgotten about Polam and didn't know the other manufacturers.
I can't tell you about any other code or markings, all I had to go by were the Ebay photos.

Again thank you for your replies.

The particular GE ECC83 on ebay appear to be relabeled Anna Seghers Neuhaus Prod RFT. Either these are RFT tubes coming via Poland or some collaboration between Polam/Telam and RFT. Bottle and internals suggest that.
Other Polish tube types we have seen seem closer to Philips construction. Have not seen a Polish ECC83 yet.
