Hi Pat - what are/is the plating layers on the turrets? Silver? I assume
the solder is tin/lead.

[TN] Black substance
Ok got a new one. Found on the plated portion of a turret a black fuzz,
also on the riveted backside and the plated portions of all of the lands
outside the soldered areas.
It cleans right off with alcohol leaves no residue, is crystalline in
structure and grows away from the metal has a coral like appearance.
I have attached pictures but Steve is off today so don't know who else can
post.
Again a 40 year old board.
Any ideas????
Pat
