allwave 12

Hello:  Client asked me to work on comatose radio inherited from grandfather.  I have worked on dozens of philcos telefunkens RCAs GEs and such but this is first time tackling a EH Scott.  The turntable is a electromatic with horseshoe magnetic cartridge.  The power amp n supply chassis had no tubes and when I put some spares I had in there the audio from "phono" input came through.  Right now nothing in the way or tuned radio from its own massive tuner.  One thing I don't get is why a 9 pin mini tube was cobbled in underneath near the AF output tubes?  Might be a 12ax7?  I got the platter to turn.  I found a schematic but it is for the record cutting version which this is not.  The speaker cone is rather shot to hell.  There was a guy here in tucson that would do those but now he is gone.  Any ideas on where to send this thing?  Thank you.

In Ohio, reception is variable on those 3 frequencies of WWV at 5, 10 & 15 MC. The 12 tube Allwave Deluxe dial for the 3  shortwave bands is just 1 -100 scale. (the 1934 model FIFTEEN for short wave is accurately calibrated in MC on the dial strip.)

Scott provided a round paper (or metal) Short Wave Station Finder to relate the 1-100 dial number to the wave length in meters for each of the 3 SW bands.. Perhaps the owner has it with the manual? photo of mine:

That finder wheel is not among these paper items.  I can figure it out I expect.  Client is not likely to try for SW DX-ing!  Thank you.

A scan of the station finder wheel can be found here... https://ehscott.ning.com/photo/albums/allwave-deluxe-station-finder.  Copy onto manila folder stock, cut out, punch a small hole in the center and fasten the two parts with a brass grommet.  You will have a virtual exact copy of the paper version of the finder wheel.

Was wondering about that so thank you; I have saved it and will print it out for the owner.
