Do you know what the other one or two do? Q302 rings a bell from earlier
internet postings. Also, can you offer any clues as to how to actually test
for, or spot symptoms for, other non-FET faults?

Q-302 is the RF amp' for the MW/LW ferrite-rod antenna. If it failed,
you would notice a loss in sensitivity for that tuning range only, not
Shortwave (above 1620-Khz), FM or AIR. As for other possible problems,
we need to know more about the symptoms to help you. For example, is the
FM and AIR reception still normal? Did you try the 'FET' test I
previously posted?



The FET "problem" with the '2010', refers to a particular transistor
located on the smaller PC board, which fails because of static
electricity on the antenna. This FET is the 'AM-RF Amp' labeled as
'Q-303' on the schematic. The original type is a '2SK152-1'. You may
have other problems with your '2010' which are not related to this FET.
