Page 5: Repair Advices
Repair advices Repairs must only be carried out by authorised personnel. Replace defective parts with SONOREX original parts only. It is recommended to limit the repair of the units to the exchange of fuses, transistors, generator PCB with base plate, the heater, transducers (without new bonding), as well as the timer. The parts mentioned are supplied as replacement parts. -
Page 6: Repairs
Repairs Check of transistors Check the transistors before exchanging, in order to save unnecessary costs. The transistors can be checked in the inserted condition: Check of the bipolar transistors (generators without ICs): 1) Diode behaviour of the paths B-E, B-C and E-C: in forward direction approx. -
