Playing Blue Amberols on a Standard D

[rocky]

I've often noted that there are many BAs that are unplayable on my Standard that play OK on my Amberola. I understand that the Model H reproducer is really designed to play wax Amberols and not BAs. I wonder if this fully accounts for the unplayability of many BAs on the Standard, or if there could be other contributing factors. In other words, if I can't play a given cylinder on my Standard, would the cylinder most likely be unplayable on another Standard?

Celluloid cylinders of all types shrink longitudinally and cylinder reproducers have limited lateral travel, the amount of which is dictated by the width of the limit loop. Small diameter sapphire reproducers such as the C, H and K have relatively narrow loops when compared to diamond A, B and C reproducers. Therefore the diamond reproducers will allow for more runout before the limit pin contacts the loop and the record begins to skip. I first noticed this when I played 2 min. Indestructables on a Fireside with a K reproducer and it took a lot of observation before I finally realized what was causing the problem. I usually play Blue Amberols with a Diamond B reproducer, thus I don't often have the problem but I do often notice that as I lift the carriage at the end of the record the weight will move to one side even though it was centered when I began playing the record.
You may want to consider installing a horizontal carriage on your Standard to allow the use of a Diamond B. I have one for my Fireside and it is easy to quickly change carriages if I want to play wax cylinders.
