Let’s Talk About Tubes

1 03 2008


The tubes in the Silvertone 1470 reflect the primitiveness of the amp’s design.  The trio consisting of a 12AU6 preamp bottle, 50C5 power valve and 35E4 tube rectifier was a feature of suggested Western Electric amplifier circuit manuals going back to the 1930’s. Many pre-war radios used this setup and it’s remarkable that the amps’s manufacturer, Danelectro, would pick this tube lineup as late as the mid 1960’s and even more remarkable that it sounds so good amplifying a guitar. 


There are a few other amps at the time that used the same tubes; Harmony 303a, Vox Student (distributed in America by Thomas Organ and not made by JMI of England) and a Gregory 007. Could they have been the same basic amp, made by Danelectro and simply rebranded?


The tubes from this 1470 are labled “Silvertone” and “Japan”. Are they the originals that shipped with the amp?
