| High Voltage Warning! |
CAUTION: This web site contains information about high
voltage electronic circuits intended for qualified service
technicians. High voltage electricity can be dangerous or
even lethal if appropriate safety precautions are not
observed. Circuits may still contain dangerous high
voltage electricity even when unplugged and switched off.
If you don't know what you're doing, don't attempt to
build, repair, modify, or otherwise work on such circuits
yourself. Any use of the information on this web site is
AT YOUR OWN RISK. The author(s) of this web site disclaim

Some of the features that are important to the sound and
character of many Rick-Tone amps also makes them very
appealing to do-it-yourself amp builders and electronic
- Minimal number of active stages between guitar and speaker.
- Use of readily available tubes and other parts.
- Overdriven tube sounds at low-Wattage 'neighbor
friendly' volume levels (most models).
- Overall simplicity of the circuit designs.
The following information was originally intended to assist
repair technicians in maintaining Rick-Tone amps, but you
may also find it useful if you are building your own
I don't have any objections to individuals building their
own amplifiers based on Rick-Tone circuits. In fact, all
of my amp circuits were inspired, in one way or another, by
the circuits of other amplifiers that already existed
before I even knew what a vacuum tube was. There is very
little original in the world of tube amplification, no
matter what some boutique tube amp builders would like you
to believe. So, please feel free to build your own amp, or
even many amps, derived from the circuits on this web site.
Even sell them commercially if you wish. I don't have a
problem with that.
The one thing I do have a problem with is when
someone uses my name or the Rick-Tone trademark without my
permission. So go ahead and build all the amps you want,
but please don't call your amp a Rick-Tone and
please don't use my name or the Rick-Tone
name or logo to describe, advertise, sell, promote, or
otherwise refer to your amp. If you have questions about
this policy, please e-mail me.
 Of course there's
always room for innovation and creativity in any
technology, even a very mature technology like vacuum tube
amplifiers. Nevertheless, the vast majority of newly
manufactured tube amps don't stretch beyond what was
already established practice by the middle of the 20th
century. My amps are certainly no exception.
