All AC power operated electrical equipment must incorporate a minimum of required safety features to protect against personal injury and property loss. These amplifiers meet or exceed all safety requirements only when used properly.

The safety features incorporated in our amplifiers are:

1. The power supplies are 100% line isolated using separate power transformers for the DC plate power supply and the vacuum tube filament supply.

2. A 1500 Volt AC HI-POT test is performed on every finished unit to ensure good electrical insulation integrity of the completed product. Prior to installation, all transformers, power and audio output are individually HI-POT tested also at 1500 Volts AC to verify their insulation ratings.

3. The steel chassis is directly connected to the AC Line Ground (only when connected to a properly wired AC receptacle) and incorporates the use of an IEC AC power inlet socket and a removable three wire IEC power cord.

4. All AC power supply components including the power cord, AC inlet socket, fusing, wiring, switches and all transformers are UL and/or CSA rated and approved.

5. All components are conservatively operated well less than the manufacturer’s specified maximum ratings. Some components by very high percentages less than the given ratings.

6. The chassis' incorporate an engineered convection air ventilation system to provide maximum cooling for all components including transformers and vacuum tubes.

7. All tubes and heat dissipating components are well spaced and are strategically located to provide maximum air flow for cooling.

8. Comprehensive product labeling indicates all required ratings, warnings, fuse ratings, tube types and locations, and all pertinent name plate information and ratings.

9. A complete detailed Owner's Manual is provided to further describe safe and proper use, care and precautions.
