“Mullard CV4024/12AT7 – These are in Royal Air Force boxes, made in Great Britain, and are WONDERFUL. Each tube wrapped with a cardboard inner liner and pin protector. This is the most popular and sought after 12AT7 ever.
Super popular for VTL, Manley, Atma-Sphere, and others. Why? They were made better. Compared to the earlier Mullard with the folded plate these consistently last longer, have a tighter triode balance, and are quieter. Just because they are not crazy expensive at the present moment don’t let that fool you. A higher price does not always mean better quality when it comes to new old stock.tubes. It means rarer. And that means maybe they didn’t make that many in the first place. This tube was standard issue to NATO forces around the world, and now that the Cold War is over we reap the benefits. But they will go up, just like the Mullard CV4004/12AX7 went up. So party on.”
