M100A The good and the bad...

I got deeper into my M100A in the last couple of days. I pulled the mechanism and spent 2 days cleaning and lubing it. Many years of gunk.

When I purchased it I noted that the colors were not changing. I now know why. The last owner put the color vinyl on the glass as the animation plate and arms is missing. The motor is there as is the angle parts that the arms bolt to.

I guess I am going to have to hunt down the plate and the arms.

On the bright side, I pulled the steel plate and looked into the amp. All the capacitors are nice and new and shinny. So, I guess I don't have to re-cap the amp!

I still need to get the thing to not cycle a record in and out constantly. The clutch is free and working. I suspect it is an adjust or a relay.

I somehow got the thing to go into play mode, how I have not idea, so I killed the motor and put in a record and the things plays good and strong.

I talked with Gary Cope who suggested that I up the input resistor if using the Thorpe and I think he is correct as it does seem to be overwhelming the amp a bit.

He also mentioned that if you add a 4" or 5" speaker in the middle of the big speaker and wire it a certain way that you can pick up 3-5K on the upper end. I may just do that.

I am hopeful that the blackhead cartridges show up and work and I will put the Thorpe in the parts box.

I have a stilly question for the forum. How the heck do you keep the glass up on a M100A? There are a couple of holes in the top and in the back that I cannot account for.

Thanks all, James

About the glass--just"flip" it up, gently, let it rest on the top of the cabinet--them thar two "holes", at one time, had "rubber bumpers" inserted in them for it to rest on--Ron Rich
