NOTE: About 40% 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.

Last tube from this lot is discounted as the Tungsram Label is mostly rubbed off (HONVEDSEG logo on the back is OK).

Brand New MINT NOS Rare JULY 1978 Tungsram HONVEDSEG ECC83 Military Production tubes. See Military Acceptance stamp HONVEDSEG on the back (tube on the right shows back view). All tubes have the SAME Date and Batch Code FC. Made in Hungary. Military tubes were subject to rigorous test and burn in process. 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 for the last tube.
