SS Switching

[MikeM]

Hey guys

I don't know much about SS stuff, and in one of my amps I am working with some relays etc..

Basically I am working from my 6.3VAC tap, rectifying it, and running that into a big cap. This will be powering a couple of opto-FETs which will be doing my switching as well as a couple LEDs.

Now this isn't really an economic solution as I battle to get a hold of these ICs and they're quite pricey when I do.

Does anyone know of any other good and economic solutions that could be run from somewhere between 5 and 10v dc (Possibly up to 50v as well).

Thanks guys
Mike
