NOTE: RFT tubes can crack if you try to force these into sockets. Be very careful and gentle when inserting or removing the tubes.

From the same lot of Item 552 except these tubes test about 15% lower than average.

Brand new, MINT NOS Late 1960s RFT ECC83 12AX7 VEB Röhrenwerke Anna Seghers Neuhaus Prod Tubes with Halo Getter. Made in E. Germany. These are in the top 2-3 desirable tubes for Guitar tone, and also work fine in Audio gear.

 

From 100 pc bulk packs, we have re-repacked these in leftover NOS boxes from other Tungsram, RFT etc. tubes that failed our tests. Labels are fragile as expected from bulk packaging and from that era.

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.

Price = $30 per tube. Select 2 for a Matched Pair.
