Chandler Little Devil Pre Amp Users Manual

Thank you for purchasing the Chandler Limited Little Devil Pre Amp. Your Devil is handmade in the USA by real
people. What does that mean? We do not use large solder or component machines that pick and solder the parts.
We pay a real person to do it like they did in the golden age of gear. We do not have most of our work done in
China only to do nal assembly in America and then call it made in USA. We do not use surface mount
components or ribbon cables that have been recently developed to shrink the size and build time of cell phones
and computers. Instead we use time proven through hole audio components, discrete transistors, and large
transformers just like they did in the golden age of gear.

At Chandler we are proud of our American made products and we hope you like them!

The Little Devil Pre uses a 100% discrete transistor circuit and specially wound transformers. Included are item
descriptions and hints to get you on your way.

Please feel free to call our shop anytime for help or questions.

POWER SUPPLY RECOMMENDATIONS­With ANY 500 modules (not just the Devils) we recommend using a rack with external supply. We feel a
power supply in such close proximity to the right hand slots of the rack can cause hum and noise oor
issues with many modules by many manufacturers. For this reason we mainly recommend the API 500v
rack with external L200 supply and the BAE 11-slot with external supply.

NOTES on BAE racks­We recommend adding a wire from Earth to power supply common on all BAE racks. In many cases hum
can be avoided and Earth to common is standard procedure on most electronic equipment.
