20) CAUTION – For rack mounted power amplifiers, keep all wiring and materials away from
the sides of the unit and allow the unit to cool down for 2 minutes before pulling from a rack
enclosure.
21) Amplifiers and loudspeaker systems are capable of producing very high sound pressure levels
which may cause temporary or permanent hearing damage. Use care when setting and
adjusting volume levels during use.
22) FCC Part 15 Compliance Statement (for digital products, as applicable) - Part 15.21: Changes
or modifications not expressly approved by the party responsible for compliance could void

Limited Lifetime Warranty (Excludes Tubes and Speaker)
The Champ amp of the late 1950s is well known as the
small-but-mighty tone machine that belongs in every
serious guitarist’s collection. The tweed Champ is a terri c
practice amp, and has been a prized possession of countless
pro players for its great sounding, low output, easy-to-record
capabilities. Most people like to turn the amp’s volume all the
way up, and to manipulate the guitar’s controls for a variety
of sounds from pristine clean to swampy overdrive. It’s a
uniquely inspiring, complex reed-like voice.
This faithful recreation of the 1957 Champ amp is not just for
collectors or retro-minded guitarists. Any player seeking the
ultimate in low-powered, top-quality tube performance need
look no further!

Technical information about your
ampli er is listed here.
Your new Stam-F1 ampli er comes equipped with the highest
quality tubes available, sourced from various manufacturers all
over the world. Because of occasional irregularities in supply,
the speci c tube type used in each ampli er is subject to
change without notice.
When replacing output tubes, please note the speci c tube
markings on the original tubes factory supplied with your
ampli er. For example, 6L6 output tube types used by Stami
include, but are not limited to: 6L6GC; 6L6WXT; 6L6C; 6L6GE;
etc. The installation of a di erent type may require signi cant
adjustment by a quali ed technician to avoid reduction in
performance and tube life.
Additionally, TubeAmpDoctor™ sorts and tests many of our
output tubes, and labels them with plate current (PC) and trans-
conductance (TC). If your amp came supplied with, for example,
6L6WXT tubes, then a new set of 6L6WXT tubes with matching
PC/TC numbers will be the perfect direct replacement.

Special Feature --- Upgraded power and output transformers
allow for 7 or 11 watt operation. Simply swap the 5Y3GT recti-
er and 6V6GT power tubes for a GZ34 rectier and 6L6WGC
power tubes and you are now operating @ 11 watts. This also
changes the tonal characteristics of the amp so try it out to see
which avor suits your playing style!
