Just a quick question for those that have used the Ei 6CA7/EL34 fat bottle. Is it as large a round as a typical 6CA7 fat bottle?

The Norh has the tubes sunk down in the chassis and the round cut-out won't accept a "true" fat bottle like a Sylvania or GE. So I was wondering before I bought the Ei's if they are in fact a big a round as the others.

    George, I'm pretty sure Brock is asking about the size of the glass, not the base.

    Brock, yes the Ei's are a true fat bottle size. Try the 6CA7 Treasures, they have a unique bottle design that would allow the tubes to sit lower.

    Thanks George and Jesse. Jesse is correct in that the Norh can't accomodate fat bottle type glass. The cut outs in the base aren't large enough and since the sockets are recessed it's too tight. I can barely fit the fat bottle Mullard GZ32 rectifier in it's place. It just fits but it's snug :biggrin:.

    On a different note do ALL Dutch (Sittard) made EL34's have a hole in the guide pin just like the British (Blackburn) made EL34's?

    Trying to date and find the place of manufacture for a pair I'm looking at. From what little I've read the Dutch tubes should also have a hole in the guide pin.

    The codes given by the seller do indicated early Dutch made as do the getters, but one tube has a hole the other has a "scored" part where the hole should be. Not paying top dollar for fakes or reissues or Matshushita made copies. I think the dbl "D" getters are the key and they are genuine.

    Anyone shed some light?

    What are the codes George?

    xFx L7x is Sittard Holland

    xFx Bxx or Bxxx is British (Blackburn)

    5xx SYA or SY0 or SY1 or SYN or very early KEX are all Eindhoven Holland

    Trying my best :smile:

    I have a package here from Dave (DAGLJAM6) which has some blue glass JJ/Tesla EL34's he found in storage. So if anyone should go home, it's me :biggrin:.

    He's the one who sold me the Norh and promised if he ran across some old tubes he'd send them.

    Outstanding seller. Dave is a great Polkie :wink:
