James, no disrespect to Zach but I believe he’s accidentally passing on an internet myth. However if he’s actually done research I’d be pleased to exchange info with him! best wishes…

Andrew Waugh,

Hey- My Bassman 20 was featured in Premier Guitar’s “Trash or Treasure” column(Feb/2014) & Zach’s (who works for “Guitar Bluebook”) research found that under 600 of these were made.@ no time did these sell for $600. The simple circuitry in these makes a great amp for recording bass & guitar. I paid $125 for mine in 1985. -Thanks-JB

James Baydarian,

I was in error. Thanks for the info! Sure sounds bigger than a 20-watt amp.

SemiDriven,

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,
