An AA6 with phono input, inconveniently switched in back.

Oh, there's the dial scale!  Nice styling. 

The glimmer of the markings is visible during the day, but this nice, soft effect is really best appreciated in a darkened room.  The dial is lit on either side with a type 1490 bulb, each just shy of a half watt.  This picture is fairly representative of real life even though it required a long exposure.

Tube Complement:
  • RF amplifier        1    12SK7
  • converter           1    12SA7
  • IF amplifier        1    12SK7
  • det/audio amp    1    12SQ7
  • audio output       1    35L6GT
  • rectifier             1    35Z5GT
The entirely octal tube complement is very unusual to see in a set of the mid fifties.

Restoration notes:

I should be able to do these in my sleep by now, but for some reason every project has to have at least one incident of very loud vulgarity, and this one was no exception.  I heated up the iron and dove in without really studying the schematic first.  If I had, I would have noticed the use of both the common ground and chassis ground symbols.  I had already finished mounting the electrolytics with a three-lug terminal strip--end lug common--when I realized my mistake.  Haste makes waste, but I was determined not to backtrack:

I took the terminal strip off the chassis and put it on an insulated standoff.  I hadn't yet clipped the old electrolytics's common lead, but it didn't quite reach.   I just added a bit of wire to the end and slipped tubing over it.  

When I got this radio it had a two-tone cord, somebody having spliced a length of black wire with plug onto a little brown stub.  In choosing a replacement I was tempted to go with black, but the brown portion was very obviously original to the radio, so I "honored" that.  One of the pilot lamp sockets was empty.  The aforementioned 1490 bulb is a very uncommon type, but I managed to aquire a pair.

The sensitivity and selectivity is as nice as one would expect from a six tube radio, with no symptoms of the dreaded silver migration disease (knock wood).  It does seem to eat the 1490 bulbs though.  As for 'Golden Throat', the tone quality is about par with a pocket transistor radio.  Passable for AM reception, frankly pretty dismal for records.
