[JMS] 90800 Coils

Gary:
Many many thanks for that information. Apparently, it helped as I was perusing through the coil stock I had for my 90800 transmitter. It appears that I now have both grid and plate coils (#43082) so I can build up at the very least, a 75 meter AM station. My plan is to build up the power supply for the transmitter and modulator and MAYBE save some space for a matching JM oscope (ala Don's great looking all Millen transmitter). BTW, where does one get a matching cabinet to stick all this rack mount stuff in? I'm looking for something tabletop compact. 73 de Cal, N6KYR.

A couple of years ago Bill Fizette, W2DGB was kind enough to send me a 
photocopy of a few pages out of a Millen catalog that included the page 
for the transmitter coils. If memory serves me right (it's been a few 
years since I owned a 90800 transmitter) the large coil on the 
transmitter came from the 43000 series and were end fed types. Here are 
the part numbers listed for the end fed types in the 43000 series:

160 meters: 43162

80 meters : 43082

40 meters : 43042

20 meters : 43022

15 meters : 43115

10 meters : 43012

There ya' go! On a related note, I'm still looking for the following 
Millen coils for my 90881 500 watt RF amp: 42160, 42080, 42040, 42015 
and 43015. Don will appreciate the significance of this next story. At 
this past AWA Conference I was rooting around in the parts surplus room 
at the museum annex looking for the previously mentioned coils (as I 
always do) when I came across the 160 meter grid coil for the amp, p/n 
43161 with the socket as well!! Needless to say I gave the museum a 
healthy monitary donation for that rare bird!
