The 2SK2975 FET's in the final stage are VERY sensitive and can easily be destroyed by high SWR, overheating, overvoltage, or voltage peaks. In the ND model Yaesu (Vertex) replaced the FETs with RD07MVS1 FET's but the problem may still exist. Be aware that the RF stage may remain sensitive to damage. The internal battery should be removed if the radio is to be stored for an extended period. In the non-ND model, a failing battery can cause the finals to oscillate which destroys the FETs. This was corrected with the ND model though it is still recommended that the internal battery be removed for extended storage to prevent this issue as well as to ensure that there is no possibility of battery leakage which can destroy internal components of the radio.
