I finished the Troubador yesterday just in time for the National League playoffs.
Most of the previous audio issues resolved when I got rid of the jumpers and temporary connections and did the final hard wiring. I also replaced the 1T5GT substitute for the detector/audio amp with the specified 1H5GT (although it probably didn't make any difference). The filament voltage/current came out perfectly with no changes--34V to the rectifier and 46mA to the other tubes. The last step was to give the tuner plates a thorough spray of CRC Cleaner.
I chose this set because it's uniquely different from everything else I have. I was surprised that any prewar radio could have been produced so cheaply. The dial face/escutcheon is cardboard stapled to plywood, and the dial is a cardboard disk with a red stripe.
The covering material is textured paper. I reaffixed the loose paper with rubber cement. Not taking chances with wetting the paper, I cleaned and finished it with plain paste wax.
The original wooden base for the chassis was getting loose, so I replaced it and added some perforations to help ventilate the two power-dropping resistors.
The set gets good clear reception of all local stations, and there's no noise at all between stations. I'm a Washington baseball fan by birth, so this afternoon I'm going to put on my lucky t-shirt (purchased at Cooperstown 25 years ago) and listen to the game.
Thanks for all the help in get this set up and running.
