Annotation

These amplifiers are the succesors of the series MAR 24/..Z. If they are used as a replacement, an additional transformer winding of 15-0-15 V / 0.5 A is required. The unit is also available under the identification MAR 25/6ABB without time limit and option of final stage interrupter in different dimensions.
