These little guys have been around since 1949 and still remain in Fenders line-up.
Though they were meant to be student amplifiers for home use, players have found out, they make excellent recording amps and even sound great when miked.
Remember, your amp is newer than the newest component.
For example, if you find pots from late ‘64 and transformers from early ’65, you can be pretty sure your amp is a 1965.
The tweed material covering the amp lasted through 1964 when it changed to the familiar black tolex. From 1955 until 1963, the covering was dark brown material. A 6V6GT became the power tube and a 12AX7 filled in as a preamp tube.
The Champ has but one 6V6 power tube and therefore a phase inverter tube is unnecessary.Except for the slightly larger cabinet, the speaker grill material, and the size of the grill, not much inside the amplifier was different.The same tube configuration existed, however they were glass tubes instead of metal envelope tubes, The speaker was still 6” and made by Jensen.Originally, it was the leather luggage style strap, this became a leather fold-down strap and finally in 1964 it was made of black plastic that folded down, typical of today’s Fender amps.The speaker started as a 6” Jensen, but as the years went by, it became an 8” Jensen.
