Am I over spec'ing this DPDT switch for my 5F6a power transformer?
I am wiring my guitar amp power transformer to handle both 120v and 220v. It has a universal voltage primary to do this.
Is this DPDT overkill at 17A 125VAC, 12A 250VAC...
Some sort of "helping hands" would help with assembly.
I don't like the normal tentacle-like helping hands, and I suggest this instead.

It'll be useful for your guitar tech work as well.
