Hi Guys, does anyone here know the proper weight for the Edison reproducer found on the 1928 models of the C-1 and C-2 radio/phonograph combinations? These units had a very clever weight adjustment for the only pickup made to play both Diamond Discs and the later Needle Cut Edisons (or the standard lateral record). I cannot find in any literature or service manual what is called for. Obviously there was an adjustment for a reason and there must be an optimum weight. The later 1929 model C-4 that played only lateral records did not have any adjustment. Also, I'm unaware of any other magnetic pickup of the day that had an adjustment for weight on the stylus, although I'm limited to other high end Victors such as the 9-16 of the same vintage. Any suggestion appreciated. Thanks Bruce
