Some delicate parts of the discrete circuitry can be influenced by the surrounding temperature easily. The main reason for this circumstance is the single transistors that can react very sensitively to variations in temperature (which can – depending on the place of installation and operating time – happen by all means).
With the T12 Heater elysia presents a system that arranges constant conditions and reduces the thermal fluctuation to a minimum. This system was inspired by high-precision measuring instruments. It features up to 12 discrete transistors in a massive copper ring that is warmed up to a definite temperature.
Once the system has reached its working temperature, it only needs little current to keep it at the same level. An electronic control circuit is responsible for a low variance of only a few degrees. The procedure is known from high end tube gear: the mpressor should be granted a short warm-up time to experience it absolute top form.
