6973 anyone?

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

Hey Jeff, I'll send you an email, that would be cool to have a couple more of those. They are interesting tubes, an input triode with the output internally wired to the input of the output pentode in the same bottle ! It's like a whole little amp in there, all it needs is an input, ground and power ! I think the ones I have are from Germany as well. In fact, the amp that uses it is a German old Hohner Concertaphon IV, a pretty neat amp that I have been meaning to post some pics of for you guys to check out. It has 3 separate chassis inside, for the preamp, power amp, and reverb unit, which even has its' own power supply and rectifier tube ! It's got a chrome or nickel plated reverb tank ! those nutty Germans...

JeffWest wrote:6973 is a beam power tube that came out in the late '50s and was promoted as an audio power tube. Nine pin base. Similar to 6CZ5 but has higher ratings, slightly different pinout. Used sporadically by Supro and has gained some notoriety in that capacity because the Supro that Page used on early Zep albums apparently ran a pair of these. Also found in some tube hi fi amps ca. '58-62.


Jeff, What is the preferred mfr. 6973 power tube in the vintage glass world (for a Supro) ? Is there a British ie. Mullard or other stong foreign version ?
