How many sets of these Kerafol Keratherm Red isolators do we need for the F5X? Can these be distribute along with the resistors or others?

In response to EUVL the above poster copied the response from about 5posts up. I added the responder to the newest list.
Also for your case do we not have at least 18 items that need an insulator? I think people should be aware of this fact at this time.
You can just buy Kerafol, but you are still charged the postage on its own.
For 2 channels F5X, you need 8x TOP3 Kerafol.
If you use the 2SK3497/2SJ618 regulator, you need for 2 channels another 4x TOP3 Kerafol.
You then also need for rectifier diodes (say MSR1560) 16x TO220 Kerafol (4x full bridge).
Then if you subscribed for my case, the protection board has 6x TO220 devices.
But then these are much less critical and you can use mice and thermal grease there.
How much you need depends on how closely you follow my design.
Minimum would be 8x TOP3 (just for the amplifier)
Maximum would be 12x TOP3 + 22x TO220.

That's quite a lot of kerafols. What's the price for these are we getting group discount from the manufacture?
I am still waiting for the US distributor to respond. So, no pricing yet, but worst comes to the worst, we have Zhou. Given this amount, maybe he will offer some discount. At the moment, everything is in flux.
I am quite busy at work today, so it is not likely that I can call MH&W in the case of they don't respond to my online request. Also, I am only requesting the 86/83 profile which can be a little over sized for TO220.

zhoufang is offering TO247-sized foils:
http://www.diyaudio.com/forums/vend...therm-red-86-83-isolators-247-1-ea-stock.html
The 86/83 designation refers to quality characteristics, not size; 86/83 being highest quality (see datasheet).
For price estimates and sizes of the TO220 and TO247 precut foils see a previous groupbuy:

If anyone else in interested in doing a TO220 Kerafol GB as well, I'd definitely be up for bunch of these (at least 100).
OK, folks. Be patient with me, Now that I know how much homework I didn't do🙂
I just called MH&W and talked to the CS lady who asked me to email a request for a quote. I plan to order 2 sizes - TO220 and TO247. Tonight, I will create a Google spread sheet and enter the data from the latest summary that I see. I will fill in the names, Mosfet set, and Keratherm TO247 columns. I will make the sheet public so that everyone can edit.
Thanks for you patient.

yep me too, i'll grab 50 at least of the kerafoils if we can get better pricing, fantastic stuff!!
Google spreadsheet is up, please check and feel free to edit to increase or to decrease your numbers. Once I get the quote from MH&W, I will post here and update the spread sheet.
Thanks!!
Thanks!!
