Is it safe, then, to assume that a combination of draws that total
somewhat less than the lower rating would not put undue stress on the

Gentlemen, thanks for all your great help!

I run a 12 Watt radio (K3/10), my LDG Z-100 tuner, and a 45 Watt amp
(Tokyo Hy-Power HL45B) on an Astron SS-12. The thing never even gets warm.

That's reasonable I think. You'd need to amass in the neighborhood of
100-120 watts demand before you'd require roughly an ampere of
current, and that should be just barely cruising for the SS-12.

The radio uses about 3 Amps on transmit. The amplifier about 5.
