Terrific work, Peter.

I had an artistic question related to all the GC PCB kits out there. The LM3875/LM3886 chip is set up with offset pins at 90 degrees to the PCB plane. How could one use one of the ready made PCBs like your mono kit and turn the chip another further 90 degrees so that it would be parallel with the plane of the PCB?

The answer could be as simple as bending the whole affair another 90 degrees but that hits me as brutish.

A more complicated answer would some kinda 90 degree PCB solderable connector with the odd 1.7mm/5mm pitch...maybe this doesn't exist.

Any ideas?

Just bend the pins, here's one example:

Nice...except I need the bend the pins 90 degrees the "other" way

In my design the LM3875 would lay parallel to the PCB hanging out the side...not bent in tucked under the PCB.

So...same approach? Bend-N-Pray?

A sorta related question to this thread...

Have you ever considered designing and making an inverted GC kit? Your PCBs super compact and simply stunning elegant.

BTW I keep buying more of your kits because I need the rectifying PCBs...not too cost effective eh?

I started with invering Clones but later switched to NI designes as I prefer them.

You should've told me you need just the PS section, I could've arranged for that. The kit shipped yesterday already.

That's OK...now I'll have 4 AudioSector LM3875 kits that will need rectifying boards in the future

Thanks again.
