I just disassembled a Columbia No. 15 Reproducer and there are, in fact, ball bearings. They look like they work just like the Orthophonic ones do, except there are screws with pivot points and locking nuts on them to hold them in place from side to side. The one on the machine pictured above looks slightly different. Not sure if there is a place for ball bearings, but who knows!epigramophone wrote:They certainly look like ball bearings, but I have never had to dismantle a Columbia No.9 as there has never been the necessity. Unlike the crumbling pot metal Victor/HMV soundboxes of the Orthophonic era, the Columbia No.9 and it's successor the No.15 are made of brass and steel.
I have always thought it odd that whilst Columbia progressed from pot metal to brass for their soundboxes, Victor/HMV regressed in the opposite direction, probably at the behest of their cost accountants.
I don't believe that either HMV or Victor could have known in advance about the instability of pot metal over time. It offered huge advantages in being able to use a casting with only a cleaning up and painting, rather than machining it. The late pot metal Orthophonic soundboxes fixed the formula & they are excellent.epigramophone wrote:They certainly look like ball bearings, but I have never had to dismantle a Columbia No.9 as there has never been the necessity.
