I purchased what I believe to be a Edison Standard Phonograph Model B. It is in pretty good shape and seems to run smooth. Above the gearing, in front I notice another set of gears which is possibly the upgrade to 4 minute cylinders. So I have three questions,
1. If the upgrade is installed to accommodate 4 minute cylinders, how does it work, in changing from 2 to 4 minute cylinders (Physically what do I turn or push to change the from 2 to 4 minute cylinders)? Or does it just take care of itself?
2. What is the proper gear cover, if any for this gearing with the add-on gears? I have the original thin gear cover but it dose not seem to fit with the extra gears on it.
3. The phonograph came with a Model C reproducer. Is it correct I need a Model H reproducer to play 4 minute cylinders? If so, does the Model H play 2 and 4 minute cylinders?
Welcome to the board! To change the 2-4 minute gearing you push or pull the upper knurled knob on the left: push in for 2 minutes and pull out for 4. Sometimes the knob is stuck and needs to be lubed a bit You need a wider cover for the gear conversion. These are available as reproductions through phonograph parts dealers. Occasionally you'll find original covers through them or Ebay. You need a model H reproducer for four-minute records. You shouldn't try to play 2 minute cylinders with it. It would work, but would wear the cylinders or the stylus. These H reproducers are commonly available through the same sources. Here's a link to a Standard B I picked up last year: www.youtube.com/watch?v=laYcsrMp83c

1) The original gear cover for Models A, B, and C was narrow and has a hole in the front and rear to be secured to the bedplate.
2) The gear cover for Amberol Attachments (the accessory 4-minute gearing) is much wider, has a gold pinstripe on each side, and slopes toward the rear when installed. No holes - just a slot on the side where a single screw secures it.
3) The gear cover for Models D onward is much the same as #2, but is flat on top when installed.
