AX84 P1-eXtreme Tube Guitar Amplifier Project
[classic projects]
[current version] [testing version] [old
versions]
Overview
The P1 eXtreme is an evolution of the P1 amplifier which pushes the
original design out to the limits and part way into HO territory, while
keeping the essential simplicity of the original P1,with the idea of
seeing see how far you could go with just two tubes.
It does this by increasing the preamp gain, with the preamp voiced
for optimum signal swing and distortion, adding a master volume control
and then an octal power tube running at higher rail voltages for a
bigger sound.
One of the great features of this amp is the way the sound can be
varied on the Gain control between clean to edge of breakup, mild
bluesy P1-style overdrive, and on to full classic M@rsh@ll-style
crunch. With hot humbuckers or a boost pedal and the gain control
cranked, you can even get metal sounds.
Features
- High voltage-gain, specially voiced preamp provides rich preamp
distortion and drives output tubes hard
- Can be used with most octal power tubes, including 6L6, 6V6,
EL34, KT66, KT88, 6550 for fatter tone. Just adjust bias resistor and
output load impedance to suit. The bigger tubes can provide giggable
volume levels.
- Gain and Master Volume controls for a wide range of tones and
sound levels, with variable proportions of preamp and power amp
distortion
- Similarity to regular P1 means that it can be built using any
common P1 layout, with only a few minor differences to take into account
Skill Level: beginner --- Status: Ready to
