Tubes Asylum Questions about tubes and gear that glows. FAQ |

A question for the knowledgeable.
Were the iconic Mullard 12AX7 10M tubes specially made, or just regular production stock selected for close tolerances, low noise, balanced triodes etc.
The examples I've seen are coded I63 which is the common short plate tube manufactured in & after 1965.
Most importantly do they really sound any better than a well balanced regular short plate Mullard?
I recognize that 10M tubes claimed a 10,000 hour life with a two year warranty, came in elaborate packaging & some had gold plated pins.
But perhaps this was a marketing strategy, a case of more style than substance?
I mean no disrespect to those who own & treasure these tubes; I simply would like to understand if there is a real definable difference between the 10M & normal Mullard production of the same era.
I have some yellow labeled Mullard ECC83 (coded I61) which sounds really sweet, & question if the 10M would be an upgrade?
Any thoughts, or experiences with the Mullard 12AX7 10M, would be appreciated.
Best Regards.
