  • Page 14: Keep Warm Mode

    Keep Warm Mode The central fluted heatsink is at the very core of the 990’s design. Firstly it forms a very rigid and inert structural spine. Secondly, it separates the AC mains and power supply from audio electronics. Thirdly, normal finned heatsinks resonate quite badly and this noticeably effects the performance of the output stage.

    DO NOT in any circumstances allow either the + OR the – outputs of the 990 to be connected to earth or each other. This may be the case with some kinds of loudspeaker switching matrix or some headphone adaptors.

  • Page 28: Cleaning

    Servicing Your Trilogy amplifier uses thermionic valves or vacuum tubes for amplification. They are the key component in realising your amplifiers very high performance. Valves have a finite lifespan and will need replacing during the lifetime of the amplifier. This lifespan depends on how long and how hard they are used. In typical use, small signal valves can last for 5000 hours.
