Less than 500 of the amps made from 1982-1983

I’ve been researching the Rivera-era range of amps since 2004 and it looks like they made around three thousand Bassman 20s. The confusion arises when people misread the tables at the back of the excellent Teagle and Sprung book – it’s easy to mistake the ‘original price in dollars’ column for ‘how many made’.

Thanks Andrew.. Great site!

18 watts??

More like 70 watts.

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

Faceplate has the following info:

120v 60Hz ~

0.7 A 70 watts

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.

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