USSA-5 PCB GB

Other Mosfet drivers will not work as-is because of the big voltage threshold difference and would change sound of the amp. Also, the ones indicated in the schematics are very very good in audio application...

For output, I do not know other double die lateral Mosfet. Vgs threshold with vertical Mosfet would require to adapt the circuit and change the sound character. Pin out of vertical is also different from lateral. The indicated transistors are very good for audio.

For the 6th group buy I am considering adding it to the 5th since tomtest requested a second set which brings us closer to 100 pcbs where the unit price is also less...

I would leave the same unit price for the buyers so I could manage to sell less than 100 pcbs without losing money...
Stay tuned.

If someone will take care of the group buy #6 then this is the beginning of the list:
1) PauloPT, Portugal - 1 set
2) Dennis Hui, Canada - 1 set
3) asanden, Netherland - 1 set
4) Patriz, Italy - 1 set
5) Niner, USA - 1 set
6) aradan - Singapore - 2 sets


Seems I am a bit late for the party. I would be in for 2 sets

Thanks Fab.
Do we expecting an invoice or we must pay just via your mail?

Thanks Fab.

I have never sent an invoice but I am afraid there would be PayPal fee for me

I think the best is that I provide by PM by email address and you pay me as a gift so no fee for me. The previous group buys were done that way.

Hi Fab

I believe you won’t know the address of the people sending you money if you choose to receive money as a gift. People sending money as a gift should write in the comment section of PayPal their name & complete shipping address and also their forum’s name.

Enjoy the 45C sticky weekend coming our way...gotta love Quebec.

Hi see the list for the actual status. Blue background color is to select the shipment type. For others the type is already selected because otherwise it was too expensive....
Bold character price is the one selected. If not, please indicate.

Fab

Fab,

My color preference for the pcb is blue if possible. If not, no problem. Looking forward to your pm so I can send the Paypal payment.

Kind regards,
Anand.

Hello everyone

Nicmac has just made available sets (QUAD: NNNN / PPPP) 2K2013 & 2SJ313 matched and guaranteed genuine.
As each set can do two USSA, it is possible to make small group purchases between you.
See you in Nicmac's signature to see the arrangements and also the other sets of transistors.

Mosfet Drivers

Thanks Project16

Another source ( liubincalvin )on the vendor bazar forum has indicated that he has plenty of these Mosfet even though is actual stock of matched quad is getting lower. He should be able to crate other matches and possibly not as matched since their use in this design. Matching is more important only at low current (from 20ma to 50ma or so).

Total amount

Hi
For clarification, the total amount to pay is in the column titled "Total (CAD)".
When you with PayPal you can select the money you want and in this case it is in Canadian money.
I will issue another updated list tonight. A lot of payments received which will accelerate the process...
Thanks
Fab

Is it too late to add my name for a stereo pair? Black, if possible.
