Switch outputs?

Instead of using separate binding posts for 4, 8, and 16 ohm outputs (TFA-204), can I use a switch? I guess it would be SP3T, right? If so, what voltage/current specs do I need?

Using ohm's law... you should be able to figure out the current of the four ohm tap with the power rating of your amplifier...

I know several builders have used switching arrangements to accomadate the various secondary impedances available. Hopefully if they read your post they can make some recommendations or provide some practical guidance.
