Yes would probably be the straight answer to that . I've had Malaysian made ones myself . In fact the first 2 new SS3900s that I bought here in Valencia in 96 were Malaysian ones . But from experience the TAIWAN ones are better quality .

The PLL is dated 52 week of 1994, so likely it was made 1995 some time.

Though Malaysian ones were not as good as the Taiwan variants it will still be better than the later CRT and Ranger badged versions with the EPT360014C or EPT360015 boards.

There is no such thing as a Fidelity 1000 which is too good to scrap.

Another question please if I may. The swr cal potentiometer I'm told it's a pull and push back in type and adjusted rf power also.
Is this correct as my switch does pull out but just rotates without any stop point.I ordered a new potentiometer too for superstar 3900 all models but doesn't pull push.

So should it be a pull push switch for rf power adjustment and swr cal too and where can I source one please if so.

If you post a picture of the rear component side of the radio then I might be able to help . You should have a wire coming off the resistor next to the AM/FM power VR that goes to the SWR switch . Some of them do have variable power on the pull control . However , others say they do , but don't . One of mine actually switches in the "PA" when you pull the control , but that's an older EPT version . If yours doesn't stop , then the switch might have been damaged at some point . It's usually just one of the tabs that needs bending back . Personally I don't like that variable power option anyway . I think the radio is best left at 4/5W . If you wind it up to max then you'll affect the AM modulation and as there's no heat sink on the back to help , then you can easily blow the PA/Regulator .
