Another great video guys.

Your kits sound good , even wonderfull meaning they play MUSIC instead of audiophile ( mostly digital) performance ...........that's rare with the choice of commercial audio grade brands on the market of today... People who love music and want to connect to the music instead of eternal analyzing the performance of their system know what to choose ........... Nos quality kept the know how of each respected brand .............becoming brare and expensive indeed but the make the difference when you use them in this kind of electronics ...........serving the music and connect to the soul of it . Thanks.......for a wonderfull job that makes it possible for many to enjoy music within the limits of our budget for the many of us .... Kind regards.

Great and informative video. Thanks. I have a pair of 6CG7 tubes with Raytheon Japan markings. I do not see any ventilation cut outs in the plates, but the tubes also have an S22 marking. They sound wonderful, and I slightly prefer them to RCA clear tops which I also have and really enjoy. I also have a single Realistic Japan which looks like a Matsushita.

I've got a Raytheon 6FQ7/6CG7 that has plates like your Matsushita.

Raytheon was and is a USA based international electronics company and they purchased many of their tubes from Japanese manufacturers, primarily Hitatchi, but probably others as well. And rebranded the tubes Raytheon. Our rule with identification is if a tube construction matches a known plant, then it doesn't matter what the label says, the construction match is always the reference.

So freaking cool. Yeah the Toshiba brand name is actually really good!! I’m rocking some Toshiba 6DJ8 at the moment. God. Makes me want to try the 6GU7 on my other tube amp. Someday..someday. 😊
