This build guide describes how to build the
N5X guitar amplifier kit from Amp Maker.
The N5X is the successor to the very
popular SE-5a 'British Overdrive' amplifier
kit. The
circuit is almost identical, but
with some of the most popular
modifications added as standard:
1. VCB for getting power valve
distortion at lower room volumes
2. Switchable boost: None/Bright/Fat
3. Bypassable tone stack for more gain
4. More power valve options:
EL84/6V6/6L6/EL34/etc
5. All popular speaker impedances
covered: 4/8/16 ohms
This build guide assumes you have
an N5X kit from Amp Maker (above), but
you can also follow the instructions if you
want to build the amp with parts that you
have sourced yourself. If so, you'll have to
adjust the build to cater for differences in
the parts you have (transformer taps,
etc). If you're building with your own
chassis, or a donor chassis, I strongly
suggest you follow the general parts
layout shown in the guide to help avoid
noise/hum/etc issues from a sub-
optimal layout.
I've tried to make this build guide as
easy as possible to follow and that means
that it contains a lot of detail, tips and
practical advice to help things go
smoothly. If you have any feedback -
please let me know.
