There seems to be a polarity reversal diode in the radio. Tested that
theory myself and it's fortunate there is apparently something in there
to keep the accidental reversal from getting a guy in trouble.

Hi Mac,
I've bought Tecsun on amazon. Are you aware that the power plug is
reverse wired? Using a wall wart other than theirs is likely to apply
the wrong polarity to it. That might blow a protection diode (if there
is one), or it could simply fry the radio.
I agree it's a very nice radio, and also a good tool for chasing RFI.

Does anybody have a source for repair of a Tecsun PL660? The one I
bought failed a little over a year after purchase but almost no use.
