If i am correct in my accounting, the Capacitors, large relays, conectors and power switch is all that is outstanding.

The components for the amplifier.
As far as I can remember the source resistors were offered via GB.

The other resistors and other main components have been offered,

The input and output FETs have not been offered, however there is consideration into how to offer them.

Additionally:

- Appropriate inrush current limiters and fuses
- fuseholder
- M4 brass hardware (standoffs, nuts, screws) for construction of PCB connectors.
- maybe terminal strips or blocks for hooking up the three transformers with mains?
- Looking at the most recent PSU schematics (which is in fact a wiring guide for the whole F5X): The AUX transformer wants to be served by its own fuse. I can't remember having seen specs for fuse and fuseholder.

anything else?

Just an update. I have put in the main order for the protection board parts, I will be putting in the secondary order soon.

So I have a question for people here. How do you want to have this stuff packaged. I am thinking of supergueing the cut tape to card, and then putting the cards in ESD shielded bags. If no-one has any issue with me using normal card here I will do so. Otherwise I will have to order in some ESD safe card, and that is inordinately expensive.

The other option is to glue the card to Aluminium or copper foil.

What would people her prefer?

no superglue.

which components are static sensitive?

Are the SMDs individually sealed in coffins from a reel? Leave them in there. Just cut off enough for each order.

Andrew T, what do you mean by sealed in coffins? If you mean in cut tape, then, no I was not going to take the parts out of the cut tape.

However as you would realise there are many different types of capacitors, resistors etc, and the markings on each of these is not prominent.

Would taping the cut tape with esd tape be more ammenable for you.

Regards.

I have only bought a few hundred smds, but all arrived still in the manufacturer's plastic strip.
These are strip of moulded little pockets just big enough to hold one component and sealed over with a strip of clear plastic.

They were supplied as cut strips with 10 or 25 or whatever. All sealed up against foreign objects touching the device or it's pins.

Just name the device on it's plastic strip.
