Toshiba SP-690

Hey there community,

I was wondering if anyone had any information/links to information on an old console system. It is a Toshiba SP-690, though I believe they were marketed as Toshiba Boston systems. It's a three piece unit, console and two speakers. I have one that I am trying to sell but I don't have any info for people that are asking so I thought I would turn to you folks. I believe it to be from the late 60's/early 70's.

Any help would be great, thanks!
Hello Tia,
I bought the same console you have a few days ago...
But I believe the amplifier (supposed to be in the cabinet below the receiver) is missing.
Can you please help me identify what was the original amplifier like for this console? 

Thanks a lot !
