Brand New, MINT NOS NIB La Radiotechnique 12AX7S CV4004 ECC83 MINT NOS NIB Special Grade 1978-83 Box Plate Halo Getter tubes. Etched Suresnes Plant France date codes.

These are very desirable tubes, next to the the earlier production
Mullard CV4035.

Box Plates are similar to Mullard CV4004 tubes. Appears that the internals were sourced from Mullard with evacuation done by La Radiotechnique. Nor surprising since both companies were associated with Philips.


NOTES:
  • Tube labels come in 2 colors - white and green. Tubes are identical otherwise, from the same revision.
  • 12AX7S printing on tube boxes is very faint - someone in the past had handwritten 12AX7S on the flaps (see picture above).
  • Printing is fragile on the labels. Handle with care.
Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester. 65% = 1000 mmhos for 12AX7 on this tester.

Single Tube = $100. Select 2 for a Matched Pair or 4 for a Matched Quad. Even odd number of tubes will be matched.
