One pair of Siemens E88CC / 6922 tubes in original long blue and yellow boxes. Serial numbers on tubes match boxes, #703544 and #703547. Gold pins w/D getter and splatter shield. The electrostatic shield between the plates is gray. 4 seams at top of tube. Tubes are from 1950's or possibily as late as 1960 because "O" getter was used from 1961. I don't know how to pin down the date any more exact. I purchased these many years ago as NOS and never used them. I'm sure from what I read they would sound great. I'll pay shipping in the US.
