NOTE: About 30% of the tubes from the same lot have sanded glass or matte finish (see 2 tubes on the right). It is not dust, so don't try to clean it.

Brand New MINT NOS 1985 Tungsram ECC83 tubes. All tubes have the SAME Date and Batch Code. 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.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. 65%=1000 mmhos for 12AX7/ECC83 on this tester.

$50 per tube. Select 2 for a Matched Pair. Even odd number of tubes will be matched.
