amps are discussed in power section output dissipation. 70 watts is the draw at the wall power.
any dual 6v6 amps will dissipate 12 to 20 watts depending on the circuit.
Hence the “20” in the name.

Wherez Waldo,

Faceplate has the following info: 120v 60Hz ~ 0.7 A 70 watts

SemiDriven,

70 watts? no way not with just 2 6v6s in the power section.

Wherez Waldo,

18 watts?? More like 70 watts.

SemiDriven,

The typo: 1983 not 1993
