A little gem!

A bit brighter sounding than the Cyrus 2, but partnered with the right equipment it's a dynamic performer. A good phono stage built in too.

Cyrus One (1990)

Thank you for sharing the manuals.

I've been using this remarkable amplifier since 1990 and have served me without any hiccups except for burnt fuses now and again. I have yet to send the amp for a major service but I think I would do it myself with the help of your shared manuals.

IMO this amp although coming into its 22 years still sounds the same as and when I bought it back in 1990 in Brighton, England. I also bought the Cyrus 780, Marantz CD62 and finally the Linn Basik Akito/K9 t-table. This setup is still with me here in Malaysia. The best combination.

re: Cyrus One (1990)

Hi Jumpstat,

I too have been using my Cyrus 1 since the early 90's and I have just found myself in the situation where I need to use it with headphones. Plugging in my 'phones doesn't cut out the speaker output (apparently by design). Do you happen to know whether it's safe to run the amp without the speakers being plugged in? I know that my guitar amp shouldn't be used without speakers. Is it the same for the Cyrus?

Thanks in advance for any help or advice that you could offer,

Matt
