DX390/ATS818 Static Damage question...

Post by Andy Domonko » Tue, 23 Feb 1999 04:00:00

I'm trying to repair a static damaged DX390 (ATS818) . FM/SW is fine but
MW is deaf. Dejanews came up empty as to which transistor is the likely
culprit. I remember reading a thread here years ago about one or two
FET's that were prone to static damage. I would appreciate any help.
Thanks!

Andy

printed on the board. it is on the board near the antenna jack.

FM and SW are fine, MW is out. I recall there were 2 transistors in the
front end, one for MW, the other for SW/FM. Q2, Q3 perhaps?
