SAFETY PRECAUTIONS

IMPORTANT SAFEGUARDS

PLEASE READ CAREFULLY ALL THE FOLLOWING

IMPORTANT SAFEGUARDS THAT ARE APPLICABLE

TO YOUR EQUIPMENT

SAFETY

1. Read the User’s Manual and refer to it frequently during your experimenting.

2. Retain the User’s Manual for future reference.

3. All warnings should be strictly adhered to.

4. Follow instructions to the last detail.

5. This product should be operated using only the type of power source indicated in this
manual.

6. Always use an electrical outlet that is grounded. If you do not know whether the outlet is
grounded, consult your electrician or local power company.

7. For continued protection against fire hazard, replace fuses with the same type and rating of
the fuses specified. When changing fuses, completely remove power from the circuit.

8. Power supply cords and all connecting cables or wires should be routed so that they are
not likely to be walked on or pinched. Pay particular attention to cords and cables at plugs,
receptacles and terminal blocks. Always use wires with adequate ratings and safety
certifications (CE, UL, etc.)

9. During operation the tubes get very hot. Do not touch the tubes since this may result in a
severe burn. Allow several minutes after removing power for tubes to cool down before
touching them.

10. Turn off the unit as soon as you stop actively using it. Unplug the power supply from the
wall during a lightning storm or when the product is to be left unattended and unused for
longer periods of time.

11. Do not use this product near water or in wet areas. Damp basements should be avoided.

12. The product should be placed away from heat sources such as radiators, heaters, stoves
or other appliances that produce heat. Also avoid putting the unit in the direct rays of the
Sun.

13. Proper ventilation is crucial for safe and reliable operation. Never place anything on top of
your amplifier that could obstruct airflow and cause the parts to overheat and damage the
amplifier. Do not place your amplifier in a rack or bookcase unless proper ventilation is
provided.

14. Care should be taken to prevent objects from falling and liquids from spilling into the unit.
Do not subject the unit to excessive smoke, dust, vibration or shock.

15. During experimenting, make sure that all jumpers are properly seated in the correct
position, that there are no foreign objects or solder bridges.

16. Always wear protective glasses and exercise caution when powering unit after any change
is made. If possible, gradually rise input voltage and look for any abnormalities – smell or
smoke, tubes overheating (excessive glow), etc.

17. Unplug this product from the wall outlet before making any changes. Wait until tubes have
cooled down.

18. When using replacement parts, be sure to use parts with sufficient voltage and power
rating and adequate current carrying capability.

19. Should it become necessary to replace your tubes, remove the AC power plug from the
wall and allow thirty minutes for the high voltage capacitors to discharge.

20. If you have any questions regarding safe and reliable operation of your amplifier, please
email us at [e-mail]
