No late;
I want to get the parcel, put into boxes needed amounts, print labels, then drive to post office and ship at once.
Do you mean gray casted with locking lid on top?
I bought some from a guy in Bulgaria.
Yes, thats it, with the spring loaded lid...
I have one, but only one.... Needs company.
And any dead (or live) tubes you want xray'd...

Let me check. I broke one last year, so probably I have one single and alone, with no company.

Thank you Peter!
But I've concluded already that 6P15P has grids better aligned and internal structure harder fixed than ordinary EL84, they are more linear indeed.

In last e-mail he said he can ship 200 only, I've asked for 100 more. Waiting for an answer.
I'll compile the table tomorrow and let's see.
I would like to get 10 if its not too late. And, I would be happy with less if there's not enough to go around.

He did not answer yet about more than 200, I suppose it is because of weekends.
Let's hope we get enough.

Wavebourn,
Thanks....I might be missing something here but may I know where/how to find out the 6J52P gain?
Not precisely symetrical but putting the old Cray to work on it the boys at the lab came up with 82.39760451. They took off for coffee break right after handing me the printout so there's noone around to confirm this.
(Hmmm, they told me it was made of wood too)

I don't know what Russian tubes are made of, but they are hard to match for sure, even when are from the same bin.
From the triode curves that Wavebourn showed, you can calculate mu and plate resistance. Remember, mu is the change in plate voltage with a change in grid voltage with current held constant. Plate resistance is change in plate voltage with change in plate current with grid voltage held constant. And transconductance is change in plate current with change in grid voltage with plate voltage held constant.
