Excellent Pair, one tube has a partially broken guide pin which is still there, visible and useable.

Test 2700/2700 & 2800/2950 where 1640 is good on a calibrated Hickok 539-B tester.

Listening tested in my personal amp for excessive noise, microphonics and good sound.

Please see our other items for more vintage tubes & audio.

Tubes guaranteed to test good or may be returned.
