The radio was made by Canada National Carbon Co. (the parent company of Eveready) in Toronto, Ontario, Canada. According to the book "Radios of Canada", Eveready produced about 10 models of radios in Canada from 1929-1930. The same model of radio, with a different cabinet, is pictured in that book. The same model was sold in the US. Apparently Eveready only produced radios for a short time in the 1920s and 30s. On page 38 of Radio Manufacturers of the 1920's volume 2, a picture of a Model 32 console is shown. It was advertised in Radio Retailing of June 1929 at a list price of $175 (without tubes).
The power supply has a pin that is inserted to select for 105, 115, or 125 volt input. A full-wave rectifier produces the B+ using the field coil for filtering. There are taps on the transformer for the 2.5 and 5 volt tube filaments.
There is a phono input, as well as binding posts for ground and short and long antennas. A long piece of wire inside the radio was apparently used as the antenna.
Somewhat unusual is the fact that it is constructed from two separate chassis which are linked together. One contains the power supply and audio output, the other has the RF amp, detector, and 1st AF amp stages. Possibly this was to allow sharing the chassis with other models.
One of the 27 tubes was missing as was the 2.5V pilot lamp. The state of the other parts is still being investigated.
Electrical restoration is just starting and will be updated as it progresses.
All tubes tested good. These old tubes do take a long time to warm up in comparison to more modern tubes. Speaker voice and field coils have continuity. I found a plot lamp that should work.
Now if I connect a short wire to the grid of the second tube I can tune in several stations and get good audio, and the volume control works. I am still missing the first RF tube. Found good coverage of how to align and neutralize TRF receives in my copy of Modern Radio Servicing by Ghirardi. I found it funny that a book published in 1936 said that TRF receivers were obsolete but that many were still being used and servicemen needed to know how to service them. I guess now it is really obsolete.
I put the chassis back together on the supporting board that in mounts on. Made some measurements of voltages during normal operation.
I noted that the tuning caps have slotted vanes which facilitate more accurate alignment over several frequencies, if needed, so that the receiver tracking can be carefully adjusted. I also confirmed that the adjustable trimmer caps inside the radio are for neutralization and match the scheme used in the Neutradyne circuit, as described in the Ghirardi book. If I turn the gain way up it appears I can get some oscillation, so neutralizing should be done.
I did some final alignment and installed the speaker and chassis back in the cabinet and took some more pictures.
The top veneer was glued down. The water stains were mostly removed and some of the cabinet was refinished with varnish and some scratches touched up with stain.
