Dual 1019 Rescue Mission

Left it running overnight, and it does seem a tad quieter when I was listening to some music. Maybe not as quiet as my 1229 or my Pioneer direct drive, but definitely an improvement over the old hard, flat idler. Maybe I’ll pull it back out for a test to see if it’s really gotten quieter later today.

Pictures, since I forgot to post them yesterday.

Interesting construction on the new idler. I wonder if it would pass more rumble it being largely metal. Look forward to OP's input in that regard.
 
After about 10 days, the audible rumble/drone is largely gone, leaving us with just 30Hz idler noise, the 9Hz tonearm resonance, cars passing by, the neighbors going at it, deer in the backyard, etc. etc. Bear in mind, this is just the vibrations from the motor that are transferred to the deck, not the actual groove noise. In terms of actual record playing, I'd say it's about as quiet as any decent belt or direct drive now. Not bad for an idler-drive changer from 1965!

One thing that is concerning me a bit more, though, is the fact that my eBay plinth is sagging in the front left-hand corner, where the motor is. I thought it was just a worn out spring, but nope! The pressboard mounting is visibly deformed, presumably from the weight of the motor pressing down on it all these years. Guess I'll have to find a new plinth or find a way to reinforce this one, if I want it to be 100% perfect.

Those united audio trapezoidal shaped plinths are prone to the spring holes tearing and sagging. I replaced the board in a couple of mine using blackboard material from HD. I don't have the measurement tools to say whether it adds or amplifies the rumble. It is more stiff/harder than the fiberboard it replaces.
