This amplification unit uses vacuum tubes to operate. Be aware that there 

are dangers involved with removal and damage to these tubes. They

operate at a high voltage, produce a large amount of excess heat and are 

made of glass. Breakage can result in lacerations from glass shards and 

danger of electrocution is present, even after amplifier has been turned off. 

Do not attempt to remove or alter any internal wiring, as components like 

capacitors can result in electrocution, even after amplifier has been

powered off.
