Would anyone happen to know if this amp actually exists? I've found pics of both the Alpha 607 Extra and the Alpha 707 Extra but google cannot find me any of the Alpha 907 Extra so I was wondering if maybe that particular model series was incomplete. Apart from a mention here: http://www.sansui.us/Issues_IntvsDomestic.htm Where there are no pics to back it up, I can find no evidence of a 907 in the 1988 "Extra" series. Plenty of the "L Extra" but none without the "L". Can anyone enlighten me?
