chinese counterfeitng

The fake cables work fine.

@whart having worked in that industry space, defense and commercial it is a known problem with much invested to keep those products out of the supply chain..... but they try and sometimes especially in Maintenance/ repair / overhaul get far along.... most get caught....

Audioquest will check this for free, have your seller ship to them before payment and IF good they issue certificates of authenticity, then you pay
IF counterfeit, AQ destroys cables....,
IF your seller puckers, consider that....,,

@tomic601 - I remembered it as a problem from some time ago when the US was attempting to negotiate trade agreements with the Far East to reduce counterfeiting-- it really gave me pause. Glad that the folks dealing with supply were screening.
As a lark, a colleague who did me a big favor on a set of NOS tubes recently sent me another set-- a pair of Mullard EF86s -- that were counterfeit, but apparently really well done, at least to the uninitiated. That’s one of the reasons I shy away from E-Bay as a source for vacuum tubes. I suspect in some cases, even the sellers aren’t aware that they are offering bogus goods.
Thanks for your post.
