For sale is the RSA Tomahawk. I bought it new and its series number is T437.
This is fantastic little amp, especially or IEMs for the following reasons:
2) Ridiculous battery life (2 AAA batteries lasted me more than 6 months, used every weekday for at least 2 hours)
To top it off, it sounds great, has that warm, RSA sound to it.

This thing sells new for $295 + shipping, so $170 + shipping is a pretty decent deal.
