Description Technical Specs
 
Brand Spanking New, MINT NOS 1964 Hewlett Packard Label Amperex USA 7308 E188CC Gold Pin Tubes. All tubes are from the Same Batch and Same Revision VR5. Labels are fragile as expected from tubes of that era.

Same Etched date code VR5 *4I and batch code 65-04 from Amperex New York USA plant on ALL tubes. Repacked in generic white boxes from bulk.

These tubes have identical date codes/batch code/machine etchings to the Amperex PQ Label 7308 tubes listed here (Item 407). It looks like that some select tubes were labeled Amperex PQ for the regular market, and other select tubes were market for HP. HP had stringent quality requirements for tubes meant for instrumentation use.

These are the Most Desirable of the American made 7308/E188CC Tubes. These early American Made 7308 tubes had white printing and vertical etched machine code.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. New E188CC tests in the 10,500 - 11000 mmhos range.

Price = $275 for the Matched Pair.
