Hi Fred,
thanks for proceeding with this GB. I have two questions:

- Should we only enter the word "confirmed" in the relevant column or should we also calculate the totals and complete these columns, too? You might have reserved the "total" columns for your final price including PayPal fees.

"Yes", "confirmed", "I do" or whatever will do 😀
For the total $$, I didn't quite figure out how to set up the spreadsheet to calculate automatically 😱 feel free to calculate. I will calculate them later if they are left blank. Yup, the total column will be including PP fee and shipping (if applicable).

I will have the grand total when I am ready to ship.
- I haven't yet ordered any pads. Is it still possible to order some? I assume yes, since the MOQ is 1000.

Yes, I am going to order 1000 TO-220-4 from MH&W, so feel free to increase the amount.

Thanks!!

Can I suggest that we set a date for final confirmation so that people can know that they have to get their act together, perhaps 1 week hence. Also mabee we should message people reminding them of this date. There seems to be 10 people who have not touched the sheet to confirm.

Sound good, I will make the real deadline next Sunday. Below are the unconfirmed, and I will PM them as a reminder of the next Sunday deadline:

chalkandalk => Mosfet set:1, TO-247 pads: 12, TO-220 pads: 22
Nikon1975 => Mosfet set:1, TO-247 pads: 24, TO-220 pads: 20
smyslow => Mosfet set:1
holminator => Mosfet set:1, TO-247 pads: 24
vitalica => Mosfet set:1, TO-247 pads: 24, TO-220 pads: 100
ramallo => Mosfet set:2, TO-247 pads: 12
oneoclock => Mosfet set:2, TO-247 pads: 12
rdk845 => Mosfet set:2, TO-247 pads: 12
ipolyakov => Mosfet set:1
gogowatch => TO-247 pads: 24

To extend the second part of this proposal a little further: Those F5X builders (perhaps participants of the GB for the test team) who aren't interested in this GB should clearly state their lack of interest in pchw's spreadsheet.

All orders are in and paid. Due to the total cost of the order, I asked to Zhou to
charge extra for insurance.

The TO-220-4 will take 4-6 weeks to deliver. So, I expect the Zhou's shipment will arrive first.

I will reopen the spreadsheet shortly to inquire shipping alternatives, namely
1. ship direct.
2. ship to region member to distribute along other F5X parts.
3. (For US F5X participants only) I can ship these items along with the chassis.

Once I have enough info, I will calculate the total for each person.

Thanks!!

I finished PRP 220R matching today and will pack them in groups of 2 channels, 3 channels, and 5 channels. While the 33R's are still not here yet, next one on deck will be the MOSFETS. Here is my diy jig for the task 🙂

Very good.

Do bear in mind that when matching at 4A, the contact resistance of your connectors will make a difference.
The sub-D connectors are probably not rated more than 1A or so.
Maybe you should consider using terminal blocks with screws.
(I know, from experience, that it is much more work ....)
