Thanks for the audiophile grammar lesson and it is certainly comforting to know that Mullard made an economy grade 6DJ8/6922 ..... but your condescending response really misses the point.All of my “garden variety†Mullards, from the highly coveted 10M Series 6DJ8s and 1958 Type 1 6922s down to the lowly PCC88/7DJ8s (yes, I own those too) have the unique ability to cast a vivid three-dimensional soundstage, while conveying a natural warmth and lush immediacy, with layers of delicate detail. Speakers become sort of irrelevant because the instruments and vocalists are right there with the listener. That’s why Mullards are so highly coveted ……. if you are not experiencing this effect, maybe its time for a component upgrade.
Unfortunately, the fragile grid frame Mullards are susceptible to microphonics when pushed beyond their limit. My merciless Cary SLP-50B makes them howl after extended use. Kevin Deal has published a list of tubes that can survive in difficult preamps:

Included on this list is the Ediswan CV5358/CV2492, which rumor has it, sounds just like a Mullard 6DJ8/6922 .... and that is what I’m seeking.
I suspect the Ediswan CV5358s shown on Kevin’s site and on teltone.com were actually made by Brimar. I also believe the GEC CV2492s I recently purchased were made by Brimar, in their Rochester factory. They are labeled KB/AD, with the AD designation indicating the vacuum pumping process was completed in the Thorn-AEI (Brimar) Rochester plant. However, Thorn-AEI had several plants in England (Tottenham, Enfield, Footscray, etc) and I’m afraid my CV2492s came from the wrong one, because they just don't sound anything like those incredible Mullards.
I’m hoping there is some marking, labeling, or physical characteristic that can be used as a guide to find the “right†CV5358/CV2492s.
Help me if you can ..... Best Regards
