Useful information for Hehku owners.
Information regarding the usage, maintenance and features of your Hehku can be found here. Remember to always and exclusively use professional services when it comes to maintenance of your Hehku – this way you your amplifier’s guarantee isn’t compromised.
Store your Hehku in dry and heated space at all times. Keep it clean, but don’t use solvent detergents to get rid of possible stains. You can grease the tolex-surface with silicone-based surface treatment agent, but don’t spray it directly into the amplifier as silicone penetrates effectively and can cause malfunctions in for instance, the potentiometers. Only a professional with specialization in tube amplifiers can take out the amplifier-part to maintain the electrical parts. The amplifiers may hold life-threatening electrical tension inside them for hours after removing the plug from power grid.
