been a great pleasure for me. When I finally started to
play the prototypes I immediately knew my team had done
a great job, to any designer of any product THAT moment
is pretty awesome, believe me. My aim of creating new
bass products with, what I think is, great style, massive
punch, warmth yet with clear tonality, and without having
to mortgage your home, had become reality. The bass

and products, and for Albion Musical Instruments to make
its impact on that market meant that our products had to
be pretty special; after the initial launch at Music Messe
2010 and the comments that people had about the range,
including those from some pretty impressive bass players,
I knew we had made something special. I hope that you
agree with that!

only differing in the power supply transformer values to
provide the required power output.
The main preamplifier and tone forming circuit section
uses 2 double triode low noise 7025/12AX7/ECC83 valves
WXEHVLQFOXGLQJWKH%DVVDQG7UHEOH(4FLUFXLWVUXQQLQJ
from a 380 volt HT power supply and DC heaters. The
output from the valve preamp circuit then passes through
the Mid circuit, which is separate from the preamp. This
mid circuit uses a very special high voltage operational
amplifier circuit in order to pass the valve tone from the
preamp to the power amp without adding extra unwanted
colouration. All it does is change the mid frequency
spectrum.
The power amplifier stage is an extremely rugged but
very musical bipolar transistor design that delivers the
wide range response required for the punch and wide
bandwidth required by today’s bass players. The power
stage is pretty much OVER-engineered to maintain
night after night of high level bass guitar playing without
compromise. As mentioned above, the power stage is
very musical, it has a very sweet tone and handles being
pushed into distortion (which is a very big test on any

ZHWKLQNLVDSUHWW\VXSHUEVRXQGOHYHO63/IRUDQG
300 watt bass rigs. To keep things cool, the power amp
is thermostatically fan cooled on a very large heatsink
– another example of our over-engineering. As with the
other power items the power transformer is also larger
than what other manufacturers put in their comparative

ABH200C & ABH300H Features and Controls
INPUT – Mono ¼”Jack socket for instrument input. Use a
properly screened “guitar” cable for interconnection. There
are many different makes of guitar cable available, ranging
from fairly inexpensive to very expensive. Each have
different characteristics, and depending on your particular
guitar will give different results, so experimentation and
help from your dealer is the best advice we can give.

In the case of the mains fuse blowing, this can be changed
by removing the power cord connector from the amplifier
receptacle and with the aid of a small screwdriver the small
drawer in the receptacle can be withdrawn allowing access
to the mains power Fuse.
WARNING! USE THE CORRECT REPLACEMENT
VALUE ONLY!
A WORD OF ADVICE about fuses – if a fuse blows
it is usually for a very good reason, it could be anything
from a voltage spike on the mains power, to a serious
malfunction of your amplifier. Fuses are there for your
protection – treat them with respect, and never replace with
the wrong value!
