TYPE / MODEL IDENTIFICATION for Rick-Tone Guitar Amplifiers |
Some Rick-Tone and Rick Campbell amplifiers are easy to
identify, and some aren't. Difficulties in identifying the
amps are often because I didn't use a consistent marking
scheme during all of the years that these amps were built.
Rick-Tone and Rick Campbell amplifiers are categorized by
type numbers. Some units have both a type number
and a model name. In some cases, identifying the
amplifier will be easy because the amplifier's identifying
information is marked on a label on the back of the
chassis. However, in some cases, especially with the older
units and custom-made units, there may be no helpful label
on the amplifier. This web page will attempt to assist you
in further identifying your amplifier.
The very earliest amps don't have any identifying
information on them at all, except my signature and
(sometimes) a serial number handwritten on the
inside of the chassis, usually written in black
permanent marker ink. These early no-label amps can
sometimes be narrowed down to a specific type number by
observing what kind of tubes are in the amp, but sometimes
an examination of the wiring is needed to determine the
type number. See the
Specs & Schematics
page for tube information and schematics for each of the
standard amp type numbers and model names. Please note
that some amplifiers were custom-made and may not match any
of the standard types shown on the schematics page.
At some point, I started attaching small labels to the
chassis of every amp I built. Let's call these
''pre-Rick-Tone'' labels. These labels contained the
phrase ''Made by Rick Campbell'' or ''Built by Rick
Campbell'' or similar, and often included additional
information like a serial number, power consumption specs,
tube placement diagrams, etc. If the serial number has no
hyphen, the amp's tube complement or wiring will probably
have to be examined to determine the type/model. If the
serial number is hyphenated, the amp type number is the
part that comes before the hyphen. For example, if the
serial number is 11-015, the amp is a type 11.
Unfortunately, the adhesives on some of the labels
deteriorated over time, so you may find some of these
amplifiers no longer have their labels attached.
Eventually I decided to put a brand name (Rick-Tone) on the
amps. The labels from this era will include the phrase
Rick-Tone along with the amp type number and often
some other information like power consumption specs,
speaker impedance, tube placement diagram, etc. If the amp
has a model name, this is usually on the label also. For
example, "Rick-Tone Type 11 Heartbreaker Amplifier
Serial No. _______." Unfortunately, the adhesives on
some of the earlier labels deteriorated over time, so you
may find some of these amplifiers that no longer have their
labels attached.
| Experimental and Custom Amps |
Experimental prototype amps and one-of-a-kind custom amps
always received a signature on the inside of the chassis,
but sometimes didn't have any outside label, even after the
standard amps started getting labels.
If you have an unidentified Rick-Tone or Rick Campbell
amplifier and would like additional information about it,
there is a good possibility that I can identify it from a
detailed description or photos. Particularly helpful are
photos of the amplifier chassis (top and bottom) and the
writing on any labels that might be attached to it. If you
can describe where and when the amp was purchased, that may
also assist in identifying it. Please send any amp
identification inquiries by e-mail .
| Sometimes the Amps Don't Exactly Match the Drawings |
Please be aware that these amplifiers underwent many changes
and improvements over the time span that they were built,
and many units were custom-tailored to individual owners'
tastes. That means the schematic drawings on this web site
may be useful as a general guide to the workings
of the amplifier, but it will be quite rare for the circuit
of your individual Rick-Tone amplifier to exactly
match the schematic from this web site. In some amps the
differences may be as simple as a few resistor values
different from the drawing, while some amps exhibit more
radical departures from the drawings.
