So they relax their guard and forget the amplifier is a ticking time bomb, waiting to explode. "Nothing wrong here, hah, that dude on the internet, he was wrong, I beat the odds!"īut there are no odds here, there is only the 100% inevitability of what is to come. then they go through a few months or weeks of slowly relaxing.and thinking everything is fine - they use the amplifier every day. The problem is that people tell themselves, ’I’ll just listen to music today and think about the required rebuild tomorrow’. it can probably perform beyond most of the mid grade crowd. With the right kind of rebuild and refreshing effort. No games there, it’s Russian roulette every time you hit the power switch. Thus, a working alpha I is likely a decent sounding budget amplifier, at the right price, but add in the fact that they MUST be recapped and very very soon.
But then again, they can be forgiven as in most cases they have this happen when they are 20-25 years old. The alpha 220 and 230 were famous for this. Basically no sign there is anything getting close to being bad and ’pop!’ at turn on, and you’ve got a blown channel. The biggest problem with them is they pop at turn on.

They are also old by any reach of that word (audio amplifier dog years) and require a full on re-capping. overall it' a very good amp.just make sure it has good ventation on the top of it or it will burn your house down. If you find one in good shape with new caps definitely buy it. It is definitely not a krell but sonically it performs pretry damn close. I played alot of music at 3/4 volume with no distortion what so ever. very low slew rate on the nikko 450 at 150 kept the dual 8 inch references in check at all times. The nuances from my speakers were nothing short of "AWESOME ". music and bass was very clean and tight! However I discovered that it had loosend the srcrews in a couple of power receptacles in the basement causing them to "arc" and eventually cause power outage in those receptacles. This amp can put out very serious power with very low noise and distorsion.
#Nikko alpha iii owners manual drivers
I had hooked it up with 4 rf klipsch 82's and one m&K 2500 dual 12 inch drivers with on board 500 watt amp. I never hooked it up to the beta pre-amp because it just looked "cheap".I took the shorting pin out of the back of my sony 909 strgx and used it as a source and pre amp into the nikko. I pray they won't go bad or, I may not be able to repair it coz they do not exist as of now, not even on eBay.
I opened it and found 6 FET pairs with 6 other transistor pairs in its phono, line and tone stages, respectively. It has body in its delivery and low distortion, Also the stage depth is the best, almost holographic if you close your eyes and attentively listen. It sounds so so not like all the other gears listed up here. The 440 had big output but all these amps have discontinued drivers and outputs. Also, best built pcb among their Beta line)Īlpha 220 X 3, 230 X 1, 440 X 1 (the 220 had best components incl wires inside, otherwise the 230 is the same. Their amps side probably was the same, Alpha I being their best, and the second best, this side of the gear category, being a far Beta VI.īeta 600 preamp (all Mitsubishi opamp inside)īeta 20 preamp (mostly discreet circuitry, with tone circuit being on two opamps, MM and MC)īeta 1 (only MM and line, but all FET and transistors inside. I think that they had their best preamp on their Beta 1, followed by Beta 20 with nothing close to being a third best. While many users of Nikko components say their preamps are nothing special and their amps are better built, I have observed the contrary.
