Anybody used Nikko amps before?

I use a Nikko 6257 Solid State amplifier. It's been going for 33 years. I built my own speakers using three Keff drivers.
I now whish to replace the amp and speakers. Any suggestions? I wish to better the performance.

hi?
i bought a nikko alpha 440 a twenty years ago(more or less) and it is still working now!!!
it sounds like a krell or a mac intosh or an australian monitor aswell!!

it s a very good amp, strong, powerful, heavy duty amp..i allways load in under 4 ohms with four 8 ohms loudspeakers of 200watts r;m;s; each in a parallel wiring. two speakers by channel.

it has never been broken sincei bought it. i use it for disco applications of public adress.

but sincea few week? it begins to work less beter.

please be so kind to let me know how to get a technical map of it or a wiring map .

that way i ll be able to repair it by myself.

meanwhile if you know somewere i can get such maps? please let me know them..

Stay away from Nikko. Low end garbage, trying to compete with real pro audio equipment!!!!! Stick with QSC, CROWN, PEAVEY, CREST, things of that nature. More money, but more reliable. Less likely to break down under heavey use!!! Remember you pay for what you get. If it sounds too good to be true, it usually is!!!!! Just remember the store you buy your amp from is in business to make money. Also a name brand company has a reputation to keep up. If they start making garbage, then who will buy it and they will soon be out of business!!!!!!!!!!!
