Marantz 1030 Integrated Amp Rear Panel Differences?

[zunde]

Sorry this may have been asked before on here but...
There is a Marantz 1030 integrated amp close by I am thinking of picking up. When looking at pictures of this unit on the web, I notice that some 1030's have main in/ pre out jacks on the back panel:

And some (including the one close by me) do not:

Was this something Marantz added to units later in the production run? Or is there some other reason some 1030's have this feature and some don't?

Thanks, I'll hang up and listen.

Only the earliest Model 1030's have the "Main In" - "Pre Out" jacks. I think they were eliminated after the first 2 years of production. - Chris

Thank you for that info!
