The TEM 3200 needs approximately 3 minutes until it is pow-
ered up and ready for use.
Important information for long-term usage
The TEM 3200 features an automatic bias control for all operating
points, and all stages are DC-coupled. Therefore the amplifier has
a quick power-up time and is fully operational after only a few mi-
nutes. It is unnecessary and not recommended to leave it turned on
constantly. Long-term usage may cause early deterioration of tubes
and thus shortens the product's life span. The increased power con-
sumption poses an unneeded burden to the environment.
