[Elecraft] Using a KX2 with an SP3 external speaker ?

[Phil Hystad]

So far, I have mostly used my KX2 with headphones but I just acquired the KXPA100 100-watt amplifier so will be using the KX2 plus KXPA100 for a backup base station.  And, I think I want to use an external speaker.  Preferably my  Elecraft SP3.

I understand that the KX2 requires the Headphones output to be amplified for use with something like the SP3.  Has anyone built their own little audio amp or maybe just purchased one for using with the SP3?

Or, any other ideas would be welcome as well.
