New Funk Firm Achromat Warped

I just got this mat for my SL-1200G and one side is warped. The mat comes with double sided adhesive discs to secure the mat to the platter. However, the adhesive is not able to hold the warped side down. Just wondering if anyone else has had this problem. I purchased it from Music Direct, I will contact them tomorrow.

I have a 3 and  a 5mm and both are perfectly flat, no adhesive needed.

The 5mm is only about 18 months old so qc on them was good at that time.

sounds like something has gone sadly wrong.

i actually bought mine from England as even with shipping it was a fair bit cheaper than music direct

Seems there is still a problem with warped Funk Achromats - just received a 5mm version for my SL1200G and warped so only contacting the platter around the inner part of the mat. The mat was shipped in a cardboard sleeve, though this looks like a manufacturing issue rather than shipping.

Very frustrating because I had a 5mm Achromat with the machined lip for my previous 1200GR that was perfectly flat - I sold that with the table thinking it would be better to have the non-lipped version for the flat 1200G platter.😠

I’ve placed the new Achromat under a stack of LP’s to see if it will flatten, but not confident.

BTW, my order was delayed from my dealer as the distributor was waiting on a shipment from the UK - so I expect this is a recently manufactured version.

Something further regarding my dish-warped Achromat. I just read the blurb sheet that came in the cardboard sleeve and it says this:

Occasionally uneven cooling results in minor warping. Like tyres, regrettably the material does not respond to being re-formed.

At least they do say: If your mat is deemed to be warped, let us know, we are happy to replace it.

Guess I'll be sending this one back. Sucks after waiting weeks to receive it.

Yikes. I ordered a 7mm red one for my SL-1210GR direct from Funk Firm, as I could only find black here in the States. Here's hoping it isn't warped...

If its the 7mm APM you may be better off as I believe that has a glass substate that I'd expect to be flat. The lipped 5mm version I had for my 1200GR was flat and very good sounding IMO - so I think you'll enjoy the results with your GR.

The one I just received was the 5mm standard foamed acrylic mat. As you can see from the pic below its dish warped and contacts the platter only on the label area. I didn't try sticking it down with the Funk supplied adhesive dots as I want to retain the ability to swap mats - plus don't know if the dots would actually hold it down. I think its unreasonable for a rigid turntable mat at this price not be flat - that's a primary criteria in my book. I contacted my dealer and arranging a replacement.
