Dear Patrick,

I know that I will heavily regret it but I am obliged to remove my name from the list.

All the Best and good luck to all of you with the project

Shipment by Courier

We have made enquiries for you for Courier charges for 500gm box to typical destinations world wide.
The only offer that will cover full compensation of the GB amount is Fedex boxes.
This will cost 610 HKD for 500gm.
PCBs are quite heavy, and we do not know yet whether it might exceed the 500gm limit.
Hong Kong postal addresses are exception and can be shiped by SF express.

I ask you to update your list if you change your mind.

We intend to ship January 2020, and ask for payment mid December.
That allows us to split the world load between December and January for other GBs.


Thanks,
Patrick

A word of warning

I have the impression that some of the subscribers are NOT DIYers with lots of experience.
If you have not been building amps for years, and do not understand circuits, please do not attempt.
This is by no means a project for beginners.
You need to understand the circuit descriptions and have the right equipment to build properly.
Otherwise it will only cost frustration for all of us, and we CANNOT and WILL NOT nurse you through by remote debugging.

We don't want unsatisfied "customers" and we don't do this for the money.
Please consider seriously before the final payment.


Thank you for your understanding,
Patrick

 

[mordikai]

I’m gonna pull out, I’ve got a lot of projects already in various states of incompletion.
Thank you

Arthur,
Please check PM.

[JBdV]

Can I use my own UPS account for shipping?

 

[EUVL]

We can ask. Most probably yes.

A couple of small amendments

We need to make a couple of small amendments.

1)
The pre-regulators operate at about 70mA and 35°C.
All our 2SK3497/2SK618's are matched at 55°C 2A.
So we cannot guarantee their match in this application.
As in the case for the Beta testers, we recommend using 2SB1559/2SD2389 instead.
They are available from Digikey and do NOT require matching.
There is NO loss in performance, and the amplifiers have further cap multiupliers close to the amp itself downstream.

We'll deduct 400 HKD from the price.

2)
Because of the cascode BJTs (or FETs, but not supplied by us), we cannot use Type 0 heatsinks.
Instead, we need to supply (a total of 4) special heatsinks for that purpose.
See attached picture.
They will cost an additional 100 HKD.

So the revised total package price of PCB and FETs together is 4700 HKD including Paypal fees and registered air mail.


Patrick
