    I sure can, its a silverfaced unit, and I'm guessing its from the 1970s as the tuning dial backlight is blue and the tuner was mated with a Hitachi IA-600 Amplifier, Also the tuner in question does have an <E-P> mark on the tag which means my tuner came from a military store originally.

    I can see the 1st two placements as UL
    That's a December 1974 unit.

    Well When I took a second look at the serial number a little bit ago I saw a UI which would of put it at September of 1974, but either way its still from 1974 and I'm glad I was able to get that sorted out, but it was rather odd that the 2 letter manufacture date prefix didn't have a space in between it and the string of numbers that followed it like the serial number on my SX-1000 TD did, which the SX-1000 TD I have is dated to February of 1969 or PB.

    So it's an I rather than L.
    I thought I saw an L.
    Anyways. Close enough I reckon.. No pun intended :D
    Don't let the spacing put you off from model to model. If the serial is there that's all you need to worry about.

    Thanks for responding. There is no plate in that location. However, there are two screws that could have held a plate at some point. There is no color variation that shows a plate was ever there.

    If there are screws still there, chances are the plate had been removed for whatever reason.

    Not so sure that unit came from a Military PX....they were all multi voltage/Hz units.

    I've seen the <ep> mark on all pioneers regardless whether it's multi voltage or not.
    Can someone clarify the significance of the
    <ep> mark ?

    Hi,
    Im a proud owner of a Pioneer SX-1980 in the U.K.
    The serial number is XL8400009S.
    Does this make my SX-1980 a very early model dating to December 1977?

    It's just had a complete & major internal recap and refurb.
    Now safe and running without any heat issues so should last me for quite a few years.
    Only upgrade/improvement done is Filter Caps up from 22000uF to 47000uF.
    No problems with any crescendo's then! Plenty on tap!
