R1155. Langite...?
 

HELLO. Inside the case of my R1155, on the rear cork, is stamped in red “AERO”. This I assume I undersatand. However also is stamped “LANGITE”. Does anyone have a clue what this might mean ( in this context). Many thanks. David

Langite is a copper mineral formed from the oxidation of copper sulphides.

Obviously, an R1155 has lots of copper wiring in it! :-) So it may indicate that sometime in its history, someone has identified such corrosion. If this radio has spent a large chunk of its life in close proximity to many lead-acid batteries in a charging room, that would explain it. The dreaded 'green spot' now springs to mind. So I suggest a thorough investigation of as much wiring as is accessible. (Err, this is an R1155 8-\).

That's an interesting article, Lawrence. Make me wonder if this R1155 has had a modification: the fitting of sheets of langite. Perhaps it is simply that that aforesaid cork sheet is, in fact, langite. :-)
To me, that last idea sounds a good deal more likely that my earlier suggestion. ;D

Sounds like cork to me - Many thanks everyone. (How dissapointing!).
