RE: Tube hoarding

Bart, hi. Some tubes have become virtually extinct because of demand: 6LF6, 7591, and so on. The OS Tung-Sol 5881 always tested like a completely different tube as I read the meters. Even more so the OS TS 6550. The transconductance made it appear to be a completely different tube compared to other 6550. Certainly the triode world has reason to celebrate the JJ Electronics 300B and 2A3. I would not have predicted such an excellent tube as the JJ 300B would be produced at such a reasonable price. The small signal tubes are the ones I think will be difficult or impossible to duplicate in this age of cloning old brands. How about the EF86/6267 or the 12AY7/6072? How about the Bendix 6900 or the Amperex 7119? What about the 50? If KR can make a PX25 they can make a 50. So could JJ. We haven't mentioned full wave rectifiers - 5AR4, 5U4, 5R4, 5V4, CV378, GZ37, and then there are the WECO tubes. How I wish JJ or someone would come out with a GZ37 equivalent that performs like the original. Ditto 5AR4. Some types will never be duplicated well. I include tube "life" as a measure of successful duplication. What's the use of buying some pretty super-deluxe tubes with fired on nomenclature and gold plated pins that won't stand up to 100 hours of use at moderate current and voltage? Sure the price of the genuine article is going to go up. The number of NOS tubes is fixed as is the attrition of same. All audio nuts should be eternally thankful for the guitar world's increasing demand for good tubes. This is a big slice of world tube demand. Just a few opinioned thoughts.
