RE: 12Ax7 Baldwin Raytheon Japan - Toshiba or NEC?

To my ears their best made | sounding tubes were produced in the Fleetwood ( code G ) | Tottenham ( code J which produced some of the earlier Tungsram tubes, which I happen to adore ) | Mitcham ( code R ), when all else fails in regards to finding these tubes?, it's best to go to the source of their origin, namely eBay U.K..

And if you'd love to hear a very similar design, as they used ( purchased ) the tooling from Mullard during the 60's, be open minded to sample a few of the Matsushita made tubes, often known as the Japanese Mullard, and for good reason I'd add........, but in truth a more balanced tube top to bottom | quieter to boot are Brimar Long Black Plates ( not Grey ) with Square Getters Circa 1950-57.
