In Reply to: "OTK" stamp posted by FenderLover on April 21, 2014 at 00:48:36:
Guys,
OTK was the soviet military procurement office testing lab(s) at the factories. Literally OTK means quality control department or some such.
The OTK stamp meant the tube passed inspection for military service. The office went out of fashion with the soviet union. Current production and post soviet production should not have the OTK stamp, unless the factory kept them and continued to use them anyway.
