Description

The 1959 Amperex EL34 / 6CA7 power tubes in this pair have dual D getters and brown bases with holes in the centering pins (Xf4 series). The white labels on the base have the GE logo, and print on the glass says "Made in Holland." Matching date codes are etched in the glass (X9L = 1959). See photo for physical condition.
 
Testing

These tubes are loosely matched for current draw (31.2 mA and 34.9 mA at 458V on the plate and -40.6V grid) and transconductance (4800 and 5000 Gm). Usually we would not call these a matched pair, but they would probably be fine in amps with individual tube bias or cathode biased. The Amplitrex AT1000 testing process includes screening for gas, heater-cathode leakage, shorts, noise, and excessive microphonics. Learn more about our testing process here.

Pricing

Price is for the pair (2 matched tubes) and includes standard testing service. Tubes ship in their original boxes with test results for current draw (mA) and transconductance (Gm).


These tubes are sold as a matched pair. Photos are of the actual tubes.
