Needless to say, my unit has not experienced blown-out FETs.
I considered buying two in the beginning in case I were ever to drop it or whatever, but have other even less expensive receivers as back-ups (never have to use them).
Loved the Kaito 1103 and the Grundig G5 (same design)
FETs in the front end blow up on both.
I’d fix them but documentation is lacking.
**** deploy a static spark to the whip antenna on a cold winter day and KApooey the Front end is gone.\
Hey, it is sensitive, LOL
