STANCOR 10P TRANSMITTER: UPDATE 11

     Mounted and partially wired the volume control, wired up more of the 6L6 RF amp last night:
     Closeup of the tube wiring.  Still have the power supply to wire up.
     Inventorying my end-link transmitter coils from Bud and Barker & Williamson, 160, 80, 20, 10 and 5 meters I have in good shape.  For 40m, I repaired a coil earlier.have nothing marked and I'll just have to see if any of the unmarked ones will hit the band.  If not, I guess I'll be making one.  (My earlier notions were incorrect.  For some reason, I thought I'd repaired an 80m coil.)

    Thank you, Jim.

    (I think I have paper originals of both; but they're not printing any more and the scans are available to anyone interested!)

    Hi Roberta! I just saw a link to your blog on the IHRS webpage and decided to check it out.

    My good friend N4LH (formerly W4FIN) started out using a Stancor 10P in 1938/39. He will be 94 next month and can still describe in detail everything about the transmitter, down to the individual components. Here is a picture of him in 1940 at his station, the Stancor can be seen around head level on his bench. http://radiorestorer.com/1940pic.jpg

    Here is a QSL from a contact which I believe he made with his 10P: http://lesnouvellesdx.fr/galerie/galerie2.php?page=oldwasqsl&pfx=ga&id=W4FIN

    Here is a somewhat related ad that I have for a Stancor 20P : http://radiorestorer.com/standardad.PDF

    Great job so far, can't wait to see the completed project!

    Wow! I hadn't checked for comments until today -- these are very nice links, Jeremy S, and it's wonderful to hear about N4LH. I had to slow way down on the restoration this winter -- my basement got down to 40 -45 and stayed there. The house was designed around a big old coal furnace and now has a medium-efficiency gas one, the kind you're not supposed to let supply warm air to the room it draws from. :( Hoping to start back up thus Spring.
