New brought to old or old brought to new? Perhaps both?

You decide.

    That looks to be some promising technology, but how do they sound?

    Interesting for sure.

    Some of my gear uses sub-miniature tubes originally designed for military use. Able to withstand a nuclear blast, good to 80,000 feet with a life span of 100,000 hours.

    That's the one I like. Military tubes are designed to withstand EMP but not sure about the human controllers. Anyway, tubes are for the ones left survived.

    Sure, most transistors stuff will just die from EMP but the military equipments will be fine. The critical ones have failsafe and redundancy build in them so no worries about EMP. :razz:

    A 6900 (5687 on steroids) used in ICBM warheads. Max altitude 80,000 feet, 500G impact load, 50G vibration acceleration. It's job, to survive until target reached and detonated. In audio applications, near twice the transconductance of a 5687. Incredible detail and dynamics. Used this in my ModWright gear.

    If you all will be so kind, what is "sub-miniature" when it comes to tubes and identifying said tubes to the naked eye?

    I'm running a Bendix Redbank 6385 designed for the same purpose in a DAC. It sounds amazing and way better than all other 5670 types I've tried including the famed WE 396A.

    That looks to be some promising technology, but how do they sound?

    You sure they'll fit? I'm no expert but I thought the tubes were very close together on Carver's amps. Yours use his chassis, correct? Here's some recent correspondence with the people from Prima Luna:

    Question;
    "I own a PL5 Amp and am currently using KT120 with no problem. As you know Tung Sol has just or will soon be releasing a new power tube similar to the KT120. The new power tube is the KT150. Has Prima Luna been given a chance to evaluate how this tube will work with its current power amp line up?"

    Answer;
    "No we have not had a chance to try them. We have seen them, and they are massive tubes... they may not physically fit sitting next to each other in the amp. Once the tubes are released, the engineers at PrimaLuna will likely do very thorough testing on them much the same way they did with the KT120s, but that will still be a ways off."
