Do military/industrial tubes sound better than regular ones ?

Give Brent Jesse a call 847 496 4546, he's the best "font of information" on NOS tubes. I will also add that in my preferred tubes are usually medical/broadcast/military......not always, but usually. The fact that those types of tubes are supposed to last longer does not hurt

I do buy tubes from Brent of Audio Tubes. From Tube Depot too, though their prices are high and choice is limited.

Medical/military/industrial must be more durable, reliable and longer lasting. They usually cost two/three times more, and as a collective expert opinion was expressed here - they might or might not sound better, could even sometimes sound worse.

Military/industrial grade NOS EL34 tubes would be very helpful, indeed. Do they exist ?

Government is inefficient right? That means less bang for the buck not more if military. 💥

mapman, you are..never mind.
