I have a couple of questions about the D10A record changer in my 47-1230.

1)  Motor mounts.  I've seen several different YouTube videos of people working on the D10 or D10A record changer and their motor mounts are exactly the same as mine.  I am certain that I have the original grommets, and they are the same as those in the videos.  In each case, the sleeve inside the grommet is taller than the grommet.  And in each video I've seen they have inserted grommets or washers to take up the extra space.  Initially I did the same...I printed some thick washers on my 3d printer using some flexible filament:

   

But after much thought I decided that the correct setup is to leave this space, so the motor is allowed to 'float'.  The result looks like this:

   

If you have worked on one of these this should be familiar to you.  I really believe this is the correct setup and intend to leave it this way.  But if someone can convince me that the first way is correct it's easy enough to change.

2)  I installed a dropping resistor in my radio which results in an AC input voltage of about 114v.  The result is that the record player runs a little slow...I think it's about 75 rpm.  I assume there is only one way to change this (other than removing the dropping resistor, which I will not do)...a smaller idler.  I'm experimenting with printing one to see if I can make it work reliably, but if that doesn't work, will I notice the difference between 78rpm and 75rpm?

3)  Record changer mounting springs.  How tight should the springs be when the record changer is mounted in the cabinet?  I'm thinking I'll tighten them enough to take up the slack, then give them another turn or two.  Sound about right?

   

I debated with myself about the correct way to post these questions...in one thread as I did, or in 3 separate threads.  What's the 'approved' way of doing this?

Thanks!
