Anybody used Nikko amps before?

Don't think that I agree with adrianbacon2. I've had a Nikko NA 2090 scince 1983. It happily runs a set of Series 2 Bose 601's and a Thorens turntable. I listen to most forms of Rock music (loudly) and the occasional classical piece. Sounds good to me, and it's been reliable. The only gripe that I've had is with the volume control. It got a bit scratchy. I had it replaced a few years ago. The Volume and Loudness are tied together so as the volume goes above 5, the loudness drops off to protect your speakers. Circuit diagrams are available from www.agtannenbaum.com/n_cat.html or www.radioera.com/n-manuals.htm.
It's good for turntables as the phono pre amp can do MC or MM catridges. I'm looking at replaceing it with a HT amp. Probably a HK. Will keep it to run a third or fourth zone.
During my saerch for HT systems, I've listened to Denon, Yamaha, Onkyo, Marantz and HK. The HK blew me away but I thought my amp was at least an audio match to all of these amps. One bonus. Its descrete amplification so if a channel blows you should be able to replace the blown bits with off the shelf components.

Thanks for the responses. I really miss my Nikko amp. At 45wpc, the amp sounded good with a pair of Titans. The only Nikko I have is there tuner, NT-890.

Nikko was origioally a component supplier for whos who of Japanese audio companies. In otherwords they made the various switches, pots, transistors, meters andwhatnots that went into Pioneer, Marantz, Fisher, JVC, Kenwood, Sherwood and others. They decided after a while to build units themselves. I think they are one of the most underrated stereo brands in history. In the early 70's I worked for a stereo chain in the Northwest. They sold mostly mid and high end stuff. I could not afford to buy any of it . I went out and bought a Nikko. I had some of the sales and repair people listen to it. They all agreed it was as good or better than all the stuff they were selling with the exception of McIntosh.

yes, a beautiful workhorse of an amp Been in constant use for 18 years. It is an alpha 230. tolerates low imp. loads very well.

I have a NIKKO ALPHA 400, a very old amplifier and its broken. It's not possible to fix this amplifier without a schematic, can somebody help me?? and send me the service manual or the schematic. PLEASE !!!
