This lessens the load on the power tubes and makes the amp run more efficiently.The Champ has but one 6V6 power tube and therefore a phase inverter tube is unnecessary.
Here we have a vintage 1951 Fender TV-front tweed Deluxe amplifier, an early piece of Fender history.Serial number 3648, original Jensen P12R alnico magnet speaker, just reconed.Amp just thoroughly serviced, grounded cord added.... A rare find as these higher watt 50's Fenders were expensive in the day.This one has that high power twin tone like Keith's.Cranked up and miked, these amps sound like a 50-watt Marshall. Most Fender amplifiers come with two to four power tubes and operate in Class AB mode.
This means the amp comes with a phase inverter tube (usually a 12AX7) that oscillates the power between the two power tubes, or two pairs of power tubes in high watt amps.
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.
With settings at 5-6 its tone is rich and sweet like a hi-fi tube... Speakers are recent Jensens, but the originals are boxed up and included, and will be shipped separately. Early '60s, JMI (Jennings Musical Industries) production, small student combo, 4 watts from a single EL84, ECC83/EF86 preamp, EZ80 tube rectifier, black vinyl, lovely brown Vox grille cloth, hinged handle, has added footswitch jack...
