Maybe. Maybe not...it all depends on how much work it takes to get going. If the PCB doesn't need much in the way of white-wires, I will definately consider offering them to DIY'ers. If it takes a lot of work to get it up and running, stable and performing well, then probably not. I can't really provide tremendous amounts of tech support.
That said, it's based on a fairly simple concept and should work very well. If I can just solve this speaker protection issue. With this relay out of the way, that's pretty much done....so now I have to complete the PCB layout and circuit design for the protection part.

Thylantyr,
I just sent you an email, please let me know if you don't get it.
Scott
I will check my email tonight.
fyi - I just finished doing my pcb layout for the Holton
AV800 amp with some extra stuff and protection circuits,
but after this discussion I'm going too examine two
different speaker relay solutions - the one that Jan mentioned
and something more generic w/gold flash contacts on silver
cadmium oxide. According to data found on search engines,
those silver cad oxide contacts do have the small signal issues,
some relays specify min. load, some don't, and there are many
relays - even ones used in exotic home amps that use this
contact material without gold... strange
I've been searching thru all the catalogs, there are some relay
vendors that give you gold flash on silver cad to minimize this
effect.... But gold gets pitted on arcs - hehe
I have space constraints on the pcb and would like to have
another option so I might layout a footprint to accomodate
two standard DPDT, 10A/contact relays all in parallel, but if there
is a failure and something weird happens, I will also have my
speakers fused. This is for DIY only.
