Brand New MINT NOS AUGUST 1972 Production Tungsram ECC83 tubes. Made in Hungary. These tubes are hard to find these days. Repacked in generic white boxes from bulk. Tungsram made some of the finer tubes in Eastern Europe due to its exposure to subsidiaries in Gt. Britain and Austria.
- Labels are fragile and not perfect as the chalky printing from that era comes off easily with contact.
- Tubes have heavy flashing pattern. Those are not burn marks. Pairs will be matched according to the test scores and not cosmetics.
