You also should try the E182CC as an output tube. Very different presentation style to the 5687 [I actually have another amp that uses both]. LD may have even started out with this tube!

Yes!
 
The E182CC has the same pinout as the 5687, so if you are using, or plan to use the 5687, you can use the same adapter. Like the Philips E88CC/6922 and E188CC/7308, this tube was manufactured both in Heerlen, Holland, and in Hicksville, L.I., NY, and I find it to have a similar sonic signature. In Europe, it was marketed as E182CC and in the states, 7119.
 
And in addition to the 5687 and E182CC/7119, you might want to consider the 7044. As best I can tell, these were manufactured only in the US by the major American companies. I have not spent much time with the 7044 (used as a driver), but from what I have read, some consider it to be a tad bit drier than the American versions of 5687.
 
Have fun!

Yes, yes, yes! Only the heater current is a bit low with 0.3 A for the ECC88.

Thought we had been here before p285, post 4360 ish! 18 month ago I was push 5687 and E182CCs as output tubes1

The ECC88, E88CC and E188CC all have a heater current of about 0.3A, similar to a 6N23P, so these are not well suited to be used as an output tubes.
 
However, the E182CC draws about 0.64A so it could be at least as good as a 6SN7, which draws 0.60A. And with a sonic signature quite different than the American versions of the 5687 and 7044, I believe it is very definitely worth a try.

Sometimes it takes a while for "pushes" to bear fruit.

Nobody seem to know anything about this tube asked in several threads . This is not really the right thread but this is a last resort you might say .Does anybody know anything about a the U54 RECTIFIER is it as good as a U52 or is it different what would be sound signature of these . would appreciate any infos you guys might have . Thanks

Those links are good for info on the tubes. As you can see they both run in 5V but the U54 draws up 2.8A and the U52 draws up 3.0A. Also the pinouts are different as you can see by the pictures. As for sound signature I have no idea; though I imagine they would sound similar but that's me guessing.

U54 seems to be the MOV type code for the Mullard GZ37. So, who made the U54 in question? Mullard? Or is it perhaps the fat Cossor?

it is labelled as a GEC  made in 1961 i saw somewhere that bite marks on corners plates makes this a  Mullard possible you think

It is a Mullard tube. 

 
 
What's the etched code on it?

 

[Oskari]

  Also the pinouts are different as you can see by the pictures.

 
One is indirectly heated and the other directly heated. That is what you can see.

I dont know

Got another one this one is suppose to be Mullard made Philips Miniwatt GZ32 also has same bite marks with RK 71 /B0E  .is it a Mullard .thanks

Ok. The U54 is a Mullard. The shape of the bottle says so.
