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?

I see to recall that the Cyrus 2 had a connection for the external
power supply (PS/R or PS/X, or whatever they called it at the
time), whereas the Cyrus 1 didn't. That was true at some point in
time, anyway - there seem to
be various generations of these amplifiers.

Thanks everyone for your help. Mission technical support have kindly
offered to send me manuals for Cyrus 1s and Cyrus 2s. Hopefully,
this might indicate which one it is but I will check the points
which have been suggested.

Thanks again,

Roger


Cyrus 1 never had a PSX port , 5 pin socket on the back . If yours
has this then it is a Cyrus 2 model .

"If the "Cyrus" logo on the front bevel is red, you have a Cyrus One
- if it is silver, a Cyrus Two."

The Mk2 models had a silver logo regardless of model , my Cyrus 1 has
this feature as well as a "flip" power switch , earlier versions had
a "push buton" switch .

My Cyrus 2 has a RED illuminated 'Cyrus Two' logo and a push-button power
switch (as well as the PSX port)
