Maplenoll models, variants and customization


Hi fellow audio-enthusiasts!

I recently purchased a Maplenoll that I believe to be an Artemis.  It is a thing of beauty!   I have planned out some improvements, and know what I need to do to make it work as intended.  Fortunately all things mechanical pass the sniff test. The platter needs a bit of work, but floats as it should.  The tonearm seems to do everything it should when supplied with air; including cueing, which is a crazy process with this turntable.   Something that I did not realize until I got the beast unpacked was that it also has a vacuum platter, which is not mentioned anywhere on the interwebs for this model.  The Opollo model has a vacuum platter, but nothing else about this TT really looks like the Opollo.  From what I have read, these TT were often modified or improved, possibly under guidance from the designer/owner of the company.  Not a lot of info on the Artemis...period.   

It has a spring-suspended plinth (1 on each corner), and an anodized aluminum face.  The main surface of the plinth is matte black.  

I'll share some pics when I get home from work to see if anyone here has some insight, or guidance on things to look out for. I'll also share restoration and improvement progress, which may be slow, but will happen.

I read through all the articles I could find here, on Google, and a handful of other audio-related forums and groups.   There are a few Youtube videos, but they are more on the “look at my equipment” side and less informative.   I’ll post some pics this weekend.   The vacuum platter part is what is throwing me for a loop.   

I’ve been working on cleaning up the platter.  It was covered in old adhesive and crud.  The vacuum seal around the platter looks like thin-wall medical tube, so should be easy ro source.  The plan is to attach an acrylic mat to the platter, with channel for the vacuum hold.   
 

 

@winerocks: To remove the adhesive on the platter, give Bestine Solvent And Thinner a try. It's designed specifically to dissolve rubber cement, and is sold at art supply houses (and Amazon of course). I regularly use it to remove price sticker residue from the covers of used LP's I buy. It's much better than Goo Gone, and doesn't damage the material it is used on.

 

The Maplenoll I owned had a lead platter.  There was a coating on it to protect the owner from exposure to the lead.  If your platter has such a coating, it might not be wise to try to remove it.

Well, looks like a fail!  
There is a big chunk of lead sandwiched between the upper and lower platters.  I have been careful to not disturb this, although by this point in my life I’m more or less pickled 🤪.  
i will not give up on pictures…it can’t be that complicated.
