PL509 40KG6 EI Yugoslavia, made in 1980s on Philips machines and with Philips materials. They were also rebranded Philips, Tungsram, Siemens, Valvo, Telefunken and AEG. In service bulk packaging.

Triple mica & dual mica construction, the best for audio use, much much better than current production clones.
