Re: Columbia Graphonola that was on CL

So far, in my relatively limited experience with Columbia Grafonolas and larger experience with Victrolas, I think the pre-Viva-Tonal Grafonolas are going to have more modest performance, at least in terms of total volume output.
My theory is that this is due to the Columbia machines having smaller diameter taper-tubes, with less "flare" as they get to the horn neck.
Aside from that, with fresh rubber in the soundbox, I think their over-all frequency response is comparable to a Victrola, or any other talking machine with a mica diaphragm.
Now, to compare apples to oranges to peaches, i have a very nice oak Silvertone upright, that is comparable in size and shape to a Victrola XI, and has decent quality Saal hardware, in good repair. This machine is noticeably softer than even my Grafonola Mignonette, let alone a Victrola XI... I think part of this may be due to probably air-leakage at the vertical swing-joint in the taper-tube...
I am a little more concerned about the alleged tracking issues with some Columbia machines that cause more rapid record wear than some other designs... I think this is more of an issue with machines whose taper-tube is mounted in the corner of the motorboard (such as my Columbia "Jewel"), as opposed to the ones with the taper-tube mounted at back-center ( as with a Victrola) .
Your results may vary...
