Old paper on Beam power tubes
I've got another old paper.
This paper, from 1938, is by O.H.Schade of RCA. This must be the original paper on the invention of the beam power tube. It's a huge 8 megabytes, and tells you more than you could imagine. As before, if you want it, post an email address. |

This is a great old paper highly recommended, especially for fans of the 6L6, and is one of my favorites. Is yours the full, or the abridged version? IIRC there were two versions of this paper, one published in the Proceedings of the IRE, and the other published in the RCA Review, I forget which was which, I think the IRE published the complete version of the paper, while RCA which you would think would have published the entire paper, published an abridged version, maybe the RCA Review ran up against its page quota for that quarter.

I need all the learning I can get. Don't we all. Not everyone is free to admit it though. The paper is definitely worth a read (thanks Rodger!). Most important to your project is a grasp of loadlines, and how they relate to such parameters as distortion, headroom and bandwidth. The precise position of each loadline should be fully justified. If any depart from authentic best practice, they should be sonically legitimised, which would be a great achievement worth sharing. Pertinent to the paper: do you have any objection to feedback as a matter of principle? Here, for comparison, is something illustrating feedback to cathode with several screen connections. Some similar, eh? http://www.ivesonaudio.pwp.blueyonder.co.uk/modal.htm cheers, Ian |

I dont know anything about the technical whatfors, but know quite well what sounds I like, and a lot about music theory as ive been performing for a very long time..but I am trying to read everything I possibly can about tubes and whatnot. I didnt get the paper he mentioned, though I posted the email damnit. |

I still read the Tao Te Ching, and the Blue Cliff Record from time to time. |
