OCCASION!I offer 220 pcs. (~ 2 kgs) vintage SIEMENS ECC81 / 12AU7 as pics. show.
Collected over decades I now solve my collection. Some of the bulbs wear other logos than `Siemens` (Telefunken, Valvo etc.) but their etched factory code is evidence for true Siemens origin!
All tubes not tested and for reasons of precaution I offer them as unspecified, but empirically most of them should be in proper condition or even like new ones!
I sell these tubes "as they are", shown and described. No warranty, no return or refund.
