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) VVR 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 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.

Happy soldering! Smile

Direct links to reference diagrams
This guide is written in several sections, ranging from a basic description of the N5X to very detailed instructions on how to build each and every part of the amplifier. I recommend following it step-by-step and paying attention to the tips and suggestions.

However, if you're an experienced amp builder, you may just want to dive into the build and do it your own way. To make that easier - and for easy reference for all builders - this, the last entry on each page, lists the important reference diagrams:

* Schematic
* Power supply board
* Main board
* Finished layout
