E188CC/7308/6922

Hi,

Trying to identify a tube. Its only markings is E188cc in white label which ressemble Siemens.No branding, nothing else on the picture but grey pins instead of gold pins which is almost universal in this type. Supposedly used in the Navy (but which one). Anybody has a knowledge of this ? Could not identify from Tubemonger or Brent Jesse.

Could be a rebranded 6dj8. I think I remember reading that if it doesn't have gold pins it is not a E188CC. Whats the getter like, any ridges on top of the glass?

Thanks for Tube world. In deed, but could not find grey pins in 7308 nor e188CC. But......after my intial post, did some research and found a comment on same tube saying they are Amperex from the 60's made for military.

Follow up. Found some posts in previous posts last april. Yes they do have ridges on top so that should point them toward Amperex or Philips. But that doesn't explain grey pins if they are Amperex.

A gentleman said they would be Sylvania because they were the only ones making grey pins in 7308. But then, why would they be marked the europeean code E188CC. Those tubes have been supposedly picked from Polaris submarines.

Siemans/RCA made in W. Germany had steel pons and so did Valvo.
