Fender Princeton

The first Princeton, the "Woody" (so called for its uncovered wooden cabinet), was the smallest of the original Fender line of three amplifiers, an incredibly basic 3-watt practice amp with no controls at all, not even a power switch.

[2] The first widely produced Princeton, the 1948 tweed-covered "TV front," used one 6SL7 or 6SC7 dual-triode tube to provide two stages of RC-coupled voltage amplification in the preamplifier section; the power amplifier section used a single cathode-biased 6V6 beam power tetrode necessarily in Class A operation.

In 1956 the Princeton received a new cabinet roughly half again as tall and wide as the previous Champ-sized "small box."

[3] This "brownface" version used a single 7025 dual triode in the preamplifier; a 12AX7 dual triode, one half of which operated a tremolo oscillator and the other half of which served as a split-load phase inverter; and two 6V6GT tubes, which were fixed-biased in Class AB push-pull configuration in the power section.

Recently, the American models made at Fender's Lake Oswego factory (branded 'LO') are becoming more sought after for their high quality and rich built-in chorus modulation.
