confused by drawing and schematic Ge model E 106
#10

Hi Dan,

+1 on Arran's comments. Almost any single ended output stage will have the cathode resistor bypassed by a rather high value electrolytic cap, especially a 6L6, as it is a rather high power tube. The value (20uF) and the working voltage (25V) are dead giveaways that this is an output tube cathode resistor bypass cap.

The same schematic can be found by searching for Canadian RCA Victor Model 10K1. The schematic and tube layout diagram are marked as for CGE Model E106, Victor (Talking Machine?) Model 10K1 and RCA Victor 10K1. The same document shows the tube layout for the CGE E157, RCA Victor 15K1, and Victor 15K1. This is a 15 tube set with Push Pull 6L6s 2IFs, separate Osc and Mixer tubes, etc. So I guess you had a choice between Deluxe and Super Deluxe.

+1 on T-Bone's comments; the Canadian GE E106 is very different from the US GE E106. The tube count and type is similar except for the front end, it has 2 IF stages, it has a 6L6 output stage but the front end and detector is quite different, as well as how bias is gotten. From 1930 to 1935, RCA built all GE and Westinghouse radios. From 1920 to 1929, Before RCA bought the Victor Talking Machine Company, GE, Westinghouse and Wireless Specialty Apparatus built all RCA sets. It seems that RCA / Canadian Victor Talking Machine was still involved with CGE in 1936.

As to why this is a single ended set, especially considering the tube count, there are those who believes that some second harmonic distortion actually sounds good. I have seen the same written by pipe organ aficionados. I expect with the separate diodes for 2nd detector and AGC, this may be a rather clean sounding set.
