Rare NOS matched and code-matched pair of Amperex PQ 5920/E180CC premium dual-triode tubes, manufactured by Philips in Heerlen, Holland.

Both tubes feature the highly desirable early pinched-waist glass construction and carry matching etched Δ7L codes, identifying Heerlen production from December 1957.

Hickok tested:

Tube 1: 2,600 / 2,800 GM

Tube 2: 2,800 / 2,750 GM

The Hickok new-old-stock reference is 2,800 GM. All four sections test strong and the two tubes are closely matched overall.

Excellent early Dutch Amperex pair for a collector, premium audio application, or vintage equipment restoration. Original lettering and cosmetic condition are shown in the photographs.

Tubes will be carefully packed for safe shipment
