SSEMBLY
Warning: This amplifier uses high voltages which could cause an electrical shock, possibly resulting in
injury or death. Therefore, these assembly instructions are intended for electronics technicians (or
those with equivalent skills) having experience with high-voltage electronics. The usual safety
procedures required when working with high voltages must be followed, and they are described only
briefly in these instructions. If you are unfamiliar with these procedures, you should not attempt
assembly. Please read through these instructions before beginning assembly. If you are in doubt
about your ability to safely and successfully assemble the kit, please send it back, or first get some
experience with other electronics kits. No liability is assumed by Tavish Design, LLC. The ARRL
Handbook for Radio Amateurs

has a useful chapter on electrical safety.
Kit assembly requires a soldering iron with a fine tip and a digital multimeter (DMM), along with other
normal electronics workshop tools.
