Group Buy for Toshiba Q-Set for the F5Pi

First of all my apologies for the delay.
Partly because I was travelling for 3 weeks, and then needed another week to get everything back to normal.
Partly also I want to wait till the GB for US version to complete first, to avoid running both in parallel.

As mentioned earlier, we can offer a maximum of 21 sets of curve tracer matched Toshiba transistors for the F5Pi.
They include :

a quad of 2SK170BL/2SJ74BL, NNPP matched for Idss, NN-PP matched for Yfs at Idss
a quad of 2SK2013/2SJ313, NNPP matched for Vgs and Yfs at 100mA at 55°C
a quad of 2SK3497/2SJ618, NNPP matched for Vgsand NN-PP matched for Yfs at 1.2A at 55°C

The JFETs and power MOSFETs have different Yfs by design, hence no NNPP is possible for Yfs.
These are the same specifications as used in our prototype.

We shall leave the GB open for 3 weeks, and then we shall call for payment and start shipping.
We do not expect all 21 sets to be fully subscribed, but then we also did not the US version to either.
The Q-sets have already been packed and ready to go any time.

Then of course you want to know how much is the damage.
Currently, the only serious offers on eBay for 2SK3497/2SJ618 are asking for 120USD per quad, unmatched, +10% shipment.
NNPP quads of 2SK2013/2SJ313 Vgs matched are 75USD a set.
And 2SK170BL/2SJ74BL Idss matched are 45USD a set.

As we offer tighter matching tolerances at working temperature, plus Yfs match, we think 2500 HKD including postage is a fair price.
This will include e-Express shipment plus fully insurance to countries where service is available.
Else they will be shipped by registered air mail.
As always we ship FOB, but will keep all shipping invoice in case of loss claims.

Because some of you have already ordered BoM from Fran, we shall deduct 100HKD from the above.
i.e. the Q-Set alone will cost 2400HKD, shipped from Hong Kong, all inclusive.
If you have not ordered BoM, please do so at Fran's GB, for the sake of tidy version management in case of need for revisions.


Many thanks for your support and interest,
Patrick


PS :
1. A complete set of the PCBs used in our prototype, including volume control, will be offered in a separate GB.
2. As Fran also knows, all our "profit" never go to our pocket, but only into future projects, with at least 5 already lined up for 2024.
