Description

Philips ECG 12AT7WC vacuum tube

There were several grades of 12AT7 type tubes. The suffix letters that follow 12AT7 designated this grading process. "WA" was a military grade tube; "WC" indicated that the US Army as well as the US Navy purchased the tube jointly. The Phillips 12AT7WC was generally used as both a driver tube in the pre-amp stage of a multi-stage amplifier as well as phase inverter applications in Class B [push - pull] amplifier circuits. Originally produced in the mid 1980s, these Phillips ECG tubes are made in the USA and ship in their original factory boxes.
