[Elecraft] KX3 (or, K3) 2-meter solid-state amplifier

[Phil Hystad]

And, there is a much better quality sheet metal brake for about $189 from Eastwood (Versa Bend Sheet Metal Brake).

I saw that Harbor Freight one for $39 but I wouldn’t buy it without looking at it (physically touching it) closely.

I built one of them and used it to form the chassis for my amp, and later on a couple other small boxes for shack utility projects. If you enjoy building stuff, creating your own brake is worth the effort. I think I made mine for less than $25. And it works pretty darn well!
