Let's see your tubes!

For some reason the pictures upside down
1)4th version
2) 1st version
3)2nd version
4)5th version
First version sound.. fantastic mid,the best I had ever heard,seductive,neutral ,tonal balance is on the warm side,smooth and relax with enough transparent when listen to single instrument without boring,if you mainly listen to vocals,nothing can beat it.
Second version... this one sounds more open and tight,good attack and more transparent,mid is clean and should suit more different system.
Forth version.. this one sounds brighter and the mid is leaner,beautiful high with tight bass,not as musical as its older brothers.
Fifth version... this one sounds not that good,the mid is cloudy and the high is hash ,bass not solid.
I did compare these 4 version few years ago and this second tested remind me that I'm right as the Mullard F31 is still the best sounding GZ34 money can buy,if someone can send us some review of the Third version will be appreciate.

for philips tubes, normally welded plate means great sounding.

Incidentally find this very early Mullard EL84 1608 L3
Made in 1953 ,small disc getter,the two lines on the plate extend to the side compare to the 1608 H4 only on the front

Date code 1608 L3

Lines on the side

1608 H4 no lines on side

This is the first time i see Mullard el84 before 1954....
1608 L3 with NO hole on the plate too?
Is the Disc getter identical to the 1954 product?
How about the sound compare to the later, like 1608 H3 no hole, 1608 with hole....

Yes,no hole on plate,the getter is different,small round disc getter. H4 have rectangular but both end are round,this L3 version looks identical to my Valvo El84 but have 8 edges on bottom mica than the Valvo's 10,only have one so don't know what it sounds like.

the disc getter looks like my 1953 philips e80cc's disc getter

Mullard M8137
First version Date code 640 R6C R=Mitcham factory,6=1956,C=March.Double support square getter,wrinkle glass.
Second version Date code 640 R6H.same as first version but top mica have more edges

HI adrianc,I found more early version Mullard M8137.produced in 1955, Date code 640 R5E with Double support square getter,wrinkle glass,and welded box plate ,I don't know is there any earlier version.

adrianc · « **Reply #669 on:** 27 Dec 2013, 01:57 pm »

Hi shoot,the R5 date code should be the earliest version and had no T mica over the top mica,some one told me the earliest version M8137 have no ribs on the plates but I have not seen one yet and doubt it.
Regards
Adrian

Hi adrianc and all Audio Circle members.
My God, how many thousand tubes do you have
in your huge warehouse?
You must have as many tubes as some dealers.
You should post a picture of your warehouse,
however, don't post your address
or you will get robbed, that's for sure.
