Snail mail would be OK, just send an email to me thru diyAudio if you wish to discuss further.

LM4780 uses tiny 2mm pin spacing so etching your own PCB or doing it on stripboard would be a real challenge.

LM3886 uses 3.4mm pin spacing so it is much easier to work with. Even point-to-point hard wiring is practical.

I saw one design that put pins onto pads on the top and bottom of the PCB - quite cool, can't remember where I saw it

hi psychocow21,

You seem a nice bloke, so PM me your address and I'll send you a couple of LM3875 PCBs. These are the very well made chipamp.com PCBs.

regards
