1966 Fender Princeton amplifier The Fender Princeton was a guitar amplifier made by Fender.
It was introduced in 1947 and discontinued in 1979.
After Fender introduced the Champ Amp in 1948, the Princeton occupied the next to the bottom spot in the Fender line.
Fender Princetons （as well as their sister amp the Princeton Reverb） from the early models into the 1970s models are highly valued particularly as recording amplifiers.
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.
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.
The amplifier had a single volume control and a simple low-pass tone control to control treble response.
The Princeton circuits up through 5C2 differed from the Fender Champ in having two versus one preamp stage （6SC7 dual-triode vs 6SJ7 pentode） and added the tone control that was absent
in the Champs; the 12AX7-based Princeton models 5D2 through 5F2-A were essentially the Champ circuits 5D1 through 5F1 with a tone control and a somewhat larger output transformer.
In 1956 the Princeton received a new cabinet roughly half again as tall and wide as the previous Champ-sized "small box." In 1961, a new Princeton （6G2） of fundamentally different design was introduced,
which instead of being essentially an upgraded Champ was more like a junior Deluxe.
This "brownface" version used a single 7025 dual triode in the preamplifier; a 12AX7 dual triode, one half of which operated a trem...
