NOTES:

• RFT tubes can crack if you try to force these into sockets. Be very careful and gentle when inserting or removing the tubes.
• Flashing pattern can vary between tubes from the same batch. It is normal.
  

Matched Pairs, Brand New, MINT NOS Late 1960s Funkwerk RFT EL84 Tubes with Alpha 6BQ5 Label. East German Production. These welded plate tubes are more desirable than the later stapled plate RFT's. Packed in generic while boxes from bulk.

Tube labels are a bit fragile since the early chalky printing comes off easily. Siemens, Telefunken amongst others also relabeled RFT tubes in 1970s-80s.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt.  65% = 7000 mmhos on this tester.
