Gold Aero tubes??


I have a pair of Gold Aero 6922 tubes with gold
pins. Does anyone know who they made by??

Thanks for any info.

If they are were relabled tubes sold by Gold Aero in the 90's they could well be Siemans (at least mine are).
Newbee,

They are in Siemans boxes, but I could not remember if I just put them in there. I have had them for a couple of years and never used them.
They say Gold Areo Selected for C.A.L. on the tubes.

Thanks
