Subject: Replacing Output MOSFETS

In the event you need to replace MOSFET transistors Q18 or Q22 as part of a repair: It is important to use ONLY the Infinity part# FE106401110, 051-640001-000, or only the brands: International Rectifier, or Fairchild. Replace both Q18 and Q22 MOSFET�s in the circuit, even if only one seems to be damaged. Do NOT mix & match these components from different manufacturers, or batches. They should be identical.
