PL519 40KG6A EI Serbia Nis

Triple mica construction, AFA Philips codes (AAA is Philips code for PL509) the best for audio use, much much better than current production clones. If you need PL509/519 for HF amplifier use dual mica version, cheaper solution. On the second photo is shown difference between older triple mica version from 80s with different heat wings and newer production from 90s and 2000+
