I believe the only difference is the colour of the base.

They were all made by Mullard UK, which was owned by Philips, Oskari knows much more than me.

When you know how to read the codes, you'll find out which factory made them, if they are correct of course!

There are short base ones brown or black, with D-Type wire or inverted cup getters, grey and black plates too.

Excellent news Glenn!

The internals are just shown from a different angle.

Including links to information about those codes.

Look-and-feel, man, and a little bit of knowledge! (Better see the other thread ^^^^^.)

Gosh, I really need to dust. 

I think I am using one of Glenn's adapters in every amp I own.

Ah.....Decware and the Mighty 596!  

Yes! Decware...

Very nice photos!

That 596 is scary!

So my initial take on the 5687 is positive.  I think the tube sounds good in the amp and is a worthy 6SN7 alternative.  Its sound is close enough to the 6SN7 that differences would be quite academic, but it is worth nothing that what I heard felt on par with my favorite 6SN7s, not just any piece of glass.  The bass is standout, it is much like the VT-231 KenRad with great drive.  Overall a nicely textured an detailed sound that is a bit on the mellow and laid back side with a bigger soundstage than most 6SN7 can throw.  Tonally it resembles a Hytron GT but without the bass rolloff and a bit different treble presentation.  They both share a creamy, textured and prominent lower midrange.

Coming off the ECC33 I thought it might be unfair, but the 5687 sounds pretty transparent and true to the music.  I would say the realism of instrument timbres was on par with my favorite Sylvania, almost on par with the BGRP Tung Sol, but this opinion lacks seasoning since I have done little comparing at this point.  I'm just taking my gut feeling from the listening session compared to how I generally feel about my other tubes.

These tubes aren't exactly dime a piece as they have their own reputation, but they do sound good.

I had the tube and made the adapter and sent it to you and never listened to the tube. Normally I don't like the sound of 9 pin tubes so I don't bather

trying them.  I guess I should have this time. I don't have a amp that uses a 6SN7 now anyway Until I make the next OTL.

   Maybe I will make one of these adapters for rosgr63 to try and see how it compares to his 6SN7s
