Brimar CV 4003 12au7 are awesome sounding audio valves ... If you can find some .... grab them ... You will not be disappointed 😎

Keep up the great work. I'm interested in getting into tube amps because of your channel.

Be careful, I dished out alot of money for these the military grade Mullard CV4003 cryo tubes, you doesn't just lose abit of air on top, it will sound very rolled off on a linear system. You lose anything resembling holographic soundstage, you get instead a very closed sound.
