 Talk about finding a time capsule! Where does one find
 spare 849s, though?


833A's.  They don't use the same mount of course, but the 849 was pretty much 
the predecessor of the 833.  I'll use the
the big bottles until they give out, or me before.

[AMRadio] Apache TX-1 for sale

2004-05-26 Thread Paul Sokoloff
Hello all,
I have an Apache TX-1 for sale.  It needs some work, but I have loaded it 
up and it is working.  The front panel is in good condition, but the cabinet 
needs painting.  Local pick-up in the Phila. area only.  It needs a new dial 
drum which are available for $23 at http://www.heathbelts.com/TX1stuff.htm and 
a tube socket replaced which has lost it's springiness.  You may be able to 
bend it back into shape.  It is the 6CL6 driver tube socket.  Picture of the 
front available or you can stop by.  Price $95.

73s

After buying several 304TH's and 304TL's, and out of five,
finding only one to be good, I'm pretty sick of it. I don't know
why I seem to end up with all the duds, but it's pretty frustrating.

-one had half the filament out
-two had a filament to grid short
-one flashes over at 500V plate voltage

I am thinking about the 3-500Z as a modulator. Any comments from
the wisdom here?

At least I can buy them new and they will have a warranty.

I suppose sockets, anode dissipators, chimneys, and chimney
hardware can't go bad, so I can't really get ripped off there..

Does anyone have a couple sets of 3-500Z socket/chimney/hardware
they'd be willing to sell?

Looking for:

-two SK410 / SK410S or equivalent air system sockets
-two HR-6 (0.6 tall) heat dissipating connectors
-two SK406 chimneys and clips for the chimneys
-Pamotor 2000 or 6500 or equivalent blower that will do 13CFM at
0.1 pressure or better

I also have a commercial RF deck with six extremely good 4CX250B
tubes and blower (it's actually a puse amp) I would trade, for
the above and a -guaranteed very good pair- of 3-500Z's.
