I have a Mission amplifier but have misplaced the instruction book. I
cannot recall if it was a Cyrus 1 or a Cyrus 2 and there are not
distinguishing marks on the amplifier. Its Serial Number is 201072C
(which makes me suspect that it is the Cyrus 2 especially since I
normally buy the best system that I can afford and this was the most
expensive of the Cyrus range at the time). Can anyone advise me or
suggest where I might find out?

TIA,
