Looking at all of the images that have been posted, that cap has a pointed nose, its conical.

Scott and Dave have kindly checked the T/S data, confirming the Gen 3 is OK to retrofit for those guys who want to swop out the old models.

Cheers

Mark,

Bring 'em on!

When do you suspect these new models will hit the retail shelves?

The rule-of-thimb i have been using is 6-8 weeks after the production run is done.

Mark,

What would be an ideal size(or range of sizes) of a sealed enclosure to house the new CHR70 Gen3?

I have a set an enclosure which may be able to house them.

Sealed sims based on the numbers from test builds using production parts.

From these, sealed can be quite a wide range.

Dave,

Thanks for your diagram.

Mark,

Will you be selling Chr70 mk 3 direct to users similar to Alpair 10.2 as an initial offer?

Yes, can do. Dan (Archer Audio) hasn't been in touch with me so I'll direct sell until he stocks. Email me - support@markaudio.com

Cheers

Hi Guys,
A quick note to let you know CHR-70 Gen 3 new coils are in from the Japan maker. We plan to final assemble commencing Thursday 26 May. Should take around 4 to 5 days. Will keep you informed.
Thanks
Mark.

Hi guys,
We're ahead of our build schedule. Take a look at the pic. That's the new look CHR-70 Gen. 3 hot off the production line. Note the change in the cap fix arrangement. We have further reduced the glue volume by designing a new jig. The method is a departure from previous where we fitted the cap and applied an external ring of glue. Now we machine apply a ring of bond on the inside of the cap, then fit it to the top of coil.

3 main advantages of the new method:

1 - The cap seal is far more reliable. We can direct check the ring bond on each individual cap prior to fitting. This ensures a 100% seal. The old method had a 12% seal error rate, now less than 2%.

2 - We use 50% less glue with this method, further help on reduce power-train mass.

2 - It looks much better than the old method.

More information coming in the following days.

Cheers

Mark.
