I am trying to repair a 85082A 2Ghz input module. The A channel is OK but the B dead. By swapping it appears that the 85082-60011 input card , of course no longer supplied, is dead. There are two critical SMC on it marked B8L and 32. I guess, the first is a diode quad and the second a FET. Could anybody give me the "normal" references. Thanks !
