Re: QSX 10W HF Linear PA kit

 

I use one that came with a Dremel. Small and handy.

I found the holes for the 0.6mm wire to be a tight fit. After making bifilar
transformer the lead wires will not be straight and they struggle to
get through the kit pcb holes.

Hans can keep this in mind!

Half kit done, rest later!

another small issue..... all holes in the heat-sink have burs on them.

You want to keep it FLAT as the devices have to be flat to it for best heat transfer.
Burs are easily removed with a precision knife (Exacto or similar).? A good builder
checks for accidental shorts prior to power up.

FYI the bigger thing is that the FBxx-2402 ferrite have sharp edges on the holes
and can strip enamel from wires while winding.? I use a small cone shaped
Carborundum stone to take the edges of the holes down.
