Ah, OK Hugh.

Hi Hugh,

It seems that the part names and values are not corresponding to the schematic in post #163. My guess is that they are corresponding to the final schematic you're going to post.

My another question is the value of C2, is it 220nf silver mica? since it's very difficult to find such a value of silver mica

Thanks,

Hi NCC,

Yes, there is always some fine tuning of the final parts list because these things are not always coordinated. Greg is the schemat man, I am the layout and parts list man. The designations are not perfectly aligned at this stage.

You can use a ceramic 220pF, or a film cap of some sort, but it has to be a small device with 5mm pin spacing.

Thank you for your interest, you are on the list which I will publish again later today.

Cheers,

Hugh

Hello

Wen I can't find silver mica cap, I use NPO type ceramic cap, they are better than standard type ceramic cap.

Good idea, Gaetan, many thanks,

If there is no objection I will send the part list to Parts ConneXtion so that we can explore the possibility of getting a package deal for all the pcb parts. With 60+ potential customers they might be interested.

Personally I like to purchase everything in one go or am I the only one?

Regards

That's a considerate suggestion but you may be stunned at the freight costs worldwide, for that sort of deal. Quite a lot of us, particularly the pros. and old hands, will already have a lot of the parts in stock or cheaply available locally. Many, even here, buy our parts in the US or Asia in economical low freight or free shipment quantities to avoid US$39 min. charges, for example.

Still, there may be a few who need this sort of help purchasing in their region.

The best source for mica capacitors is Farnell / Electronic Component Distributors / Suppliers / Electronics, Electrical Parts, Electrical Components and Wholesale Electronics.

Hugh,

I've been looking a sourcing parts - made a blog for what I've found. Mouser has the 2sk170 gr and zvp2110 but only in the TO-92 package, the sot is backordered until september. I was wondering if you could include holes for T2, so that users could use either the TO-92 or SOT packages. I'm hoping that we can find most of the parts at Mouser except for the Laterals... I would volunteer to make a spread sheet BOM for a Mouser order.

Thanks,

Ken

A mouser parts list would be a very helpful indeed. Would it be possible to add the sk170gr to the proposed parts kit?

The other thing is it would be handy to have a recommendation for the transformer, VA rating etc etc....
