6SN7 Tube Addicts
Nov 1, 2011 at 6:48 AM Post #1,336 of 7,413
Dear Blackmore,
   Thanks for the info.   I would not do crazy purchase.
   I have not been told about the price yet.  I will ask him about the plate.
   What is the difference between the Harleem made, Eindhoven  ....... Philips Pope, Philips Miniwatt,
Chelmer  .   I also read once in the upscale audio once that the Pope 6SN7 is one of the best sounding 6SN7
but the seller (not upscale audio, they won't sell without another purchase of audio) asked for very high price so
I did not buy that one.

[size=small]Philips Electrical Industries Ltd acquired a controlling interest in British Tungsram in 1952 and arranged for Mullard to take over its management.[/size]
[size=small]It ceased manufacture at the end of April, 1956, when the factory was closed and the production of Tungsram valves was taken over by Mullard.[/size]
[size=small]If the tubes were made after 1956 they cannot be Tungsram but Mullard.[/size]
The date codes will give us the clue.

The seller said that in fact the tubes are made from Eindhoven , Holland and they have logo on the tube
and he do have the original box.
I was offerred by another seller about the Philips Pope 6SN7 GT but he would like to sell by quad which I don't need
that much, here are the pictures:

[size=10pt]Maybe it's me, but in my opinion MINIWATT is the same tube as POPE, cos the last one is the commercial brand only, so, the sellers taking a huge advantage of the very small batch that been possibly made, that's all. To say that they are the best sounding is one or two man opinion, because not that many others own one and that's what makes some of us crazy. To me, give me more Mullard, Fivre or Brimar made, also not cheap, but much more available and easy to get.[/size]
[size=10pt]I owned MINIWATT ones, not 6SN7, but ECC82 or ECC83, don’t remember exactly, found them nothing special, sonically I mean.[/size]

For these Tungsram's,   I like it more than the Fivre that I purchased at the same time and may be more
than the Brimar 6sn7 long bottle.   Those are good tubes though.
I do have the Philips Miniwatts ECC32 and ECC33 ,  I think they are similar to the Mullard's  sonically.
I don't know about the Pope but at the time the seller wanted to sell as a quad abd I didn't want to
use that much money , may be  a pair should be enough for me.   I tried to take a look how much was
the asking but did not get that info.

I suppose that should be Heerlen instead of Haarlem, both cities in the Netherlands. Philips had a major tube plant in Heerlen. I cannot comment about differences between plants in Heerlen, Sittard, Eindhoven or anywhere else.
 
Philips, Miniwatt, Pope are all just brands of the company. Philips also happens to be the name of the company, in short form, that is. The brand printed on a tube doesn't guarantee much of its origin, if anything at all.

The first one looks like this one http://natubes.com/data/images/product/large_193.gif , so, I think its Tungrsam as well.

It is actually the right one that has a matching construction. The left one has a different plate structure.
 
Different versions made by British Tungsram perhaps? Or something completely different?
 
This, by the way, is supposed to be a Tungsram 6SN7GT made in Hungary:

Did CCCP make tubes for  Tungsram?
Look at the plates of the tube on the right (Tungsram, Selectron by FIVRE, Tungsram).
BTW I don't care much about Tungsram either and are nowhere near as nice as the tubes Blackmore mentioned.

Did Ken Rad make tubes for Brimar?
 
This pair, is labeled Brimar with grey glass which is uncommon for Brimar and a silver band at the bottom of the glass typical of Ken Rad.

I expect Brimar to have round plates, but they do look like RCA as well, however the base is not typical RCA?, mean, RCA's is shorter.
