What tubes do Fender amps use?
12AX7 (ECC83) Preamp Tube It is a vital component in a tube amplifier. Virtually every Fender, Marshall, Mesa Boogie, Vox, Peavey and other tube amp has at least one, and as many as five, 12AX7 preamp tubes.
What tubes are in a Fender Super reverb?
The reverb circuitry consists of two tube sections (reverb driver V3 and reverb recovery V4) and the physical reverb tank. All these components will drift during age and minor differences in component values are noticeable to man’s ear.
How many ohms is Fender Princeton Reverb?
Fender ’65 Princeton Reverb 12-watt 1 x 10 Tube Combo Amp Features: Series: Vintage Reissue series. Tube amp. 12 watts into 8 ohms.
What is the difference between 6L6 and 6V6 tubes?
What is the difference between 6L6 and 6V6 tubes? The 6v6 is only designed for a max signal power of 5 watts output while the 6L6 can handle 10.8watts of maximum power output. If you want more headroom use the 6L6 (higher wattage tubes), if you want to break up at a lower volume, use the 6V6.
Is 7025 the same as 12AX7?
The ECC83 (12AX7) Valve The answer is simple. In ‘theory’ you’ll get a bit lower noise and lower hum with a 7025. Otherwise, they are identical.
Do tubes sound different?
Most of us have experienced a noticeable change in sound quality when changing tubes. Although these changes are almost always attributed to the tube alone, it’s not that simple. Actually, it’s not the just tube— The difference you hear is tube/amp interaction.
How do I choose amp tubes?
For those just looking for a new set of tubes to get your amp back up and running, look into the tubes the amp came with and start from there. If you want the same sound, get the same or very similar tubes. If you want to experiment, try other brands or styles of the same type of tube.

How many ohms is a Princeton?
You just have to consider it the speaker/speaker cabinet will match in impedance. The Princeton has an impedance of 8 ohms, which is paired with an internal 8 ohm speaker. So it matches. If you want to use an external speaker can in addition, make sure that speaker or cab is also rated at 8ohms.
Can I use 6V6 instead of 6L6?
The general answer is no, for the most part, 6L6 and 6v6 tubes are not interchangeable as they don’t bias close enough. Amps are calibrated to use specific valves (6v6, 6L6, EL84, etc.)
Why did Fender stop making Princeton Reverb?
Much of this is due to an unefficient phase inverter circuit design. Compared to many bigger Fender amps the Princeton Reverb (PR) wenr through the CBS/silverface periods with very little changes. The rectifier tube was one of the tube and circuit changes where the 5U4GB was replaced by a GZ34.
Are Silverface Princeton Reverb amps any good?
Still, many people consider the tone of the silverface Princeton Reverb just as good as the blackface. Being almost a blackface amp with a “wrong” faceplate, the large number of silverface models became popular player’s amps. Lot of value-for-the-money.
What volume do you play your Princeton reverbs at?
Personally we mostly play our Princeton Reverbs at volume 5-6 with a decent amount of tube amp distortion (caused by preamp, power amp, transformers, rectifier all together). The amp delivers a thick sustaining tone where single notes are clean and chords are crunhcy.
