    Nikko Guru?

    Just picked up a Nikko NR-1219. I've been after one for awhile. She needs a little TLC but holds a lot of promise. I've searched the forums and see quite a few members mention the 1219 here and there, but I haven't noticed that anyone has any particular subject matter expertise for Nikko's...

    Nikko Alpha 440 Filter Caps Question

    I'm going to replace the filter caps on this Alpha 440 I have and wanted some advice. I think I know the answer, but just want to make sure, The original caps are Chemicon 40 mm X 100 mm, 100v - 15,000 uF, but they have 4 leads.

    Nikko Alpha 440 Output Transistor Subs Question

    I have an Alpha 440 with a blown channel that was going to be pitched. I hated to see it recycled for the 30 pounds of aluminum in it. I took it because it's in perfect shape,other than the blown channel and FREE. I've been searching thru the posts and just want to verify that the Sanken 2SA1215...

    How to update a vintage amp?

    Vague question, I know. Are there any threads out there indicating how to determine what to replace, what to replace it with, and how to replace it? I'm completely new to circuitry stuff, so approach as if I know nothing, which is pretty accurate. I'm trying to update a Nikko Alpha 1 and Beta 1...

    Fisher CA-880 (First Project)

    Hi all! I am new to the forum! I am taking on my first project in my quest back to vinyl and more importantly back to vintage sound! I have owned an MCS 6700 for as long as I can remember and it is still in phenomenal shape! The old SHURE RXT5 cartridge that was in there had seen better days...

    Nikko vs. Mitsubisi

    As I get back into audio equipment I need to decide if I want to have a matched set of separates or keep my mis-matched set. I have a Nikko Alpha II amp and a Mitsubisi DA-P30 pre-amp. If I located a Nikko Beta II or a Mitsubishi DA-A30 amp which would be the better set?

    Recapping vintage Nikko separates

    Hello. I am pretty new with rehabbing vintage gear but recently (and successfully) recapped a Marantz 6300 with no issue. My question is, I just got a free Nikko Alpha 220, Beta 20, and Gamma 20 set. I know they aren't amazing but free is a pretty good price. I'd like to do a recap of the preamp...

    Nikko Beta 30 relay

    Hi I've read a few threads on this: the relay on my Nikko Beta 30 Pre amp is acting up and cutting out the audio haphazardly. When I tap on the relay with the handle of my screw driver, thump and the audio clears up. I sprayed it and it got better but still cuts out and needs replacing. What...

    Hot speaker relay

    I have a Nikko TRM-750 integrated amp. There is a 560/2W (R761) resistor right next to the speaker relay that gets too hot to touch, and the relay itself ends up very warm, but not hot, after 30 minutes. It looks like this resistor brute force drops the B+ down to 24V for the coil. It is only...

    Nikko NR 1219 Repair! Loss of Right Channel, both channels work with Mono

    Hey guys I was hoping to get some help with a repair job. I just bought this receiver a month ago so I'm pretty bummed to be having issues already. As the title reads it is a NIkko NR 1219 and slowly over a day or two the right channel would go very quiet and be very distorted, Now it is...

    Nikko NR-1019: Inspiration and Imitation

    So I was shopping around for a decent power vintage receiver to further warp my son-in-laws brain and get him into old HiFi gear. Saw a Nikko receiver on the Bay, but had never heard of the brand. I did some Googling and saw this great pic of one from somebody's who's obviously very good with...

It had several of the problems that old monsters commonly exhibit, which I took care of without too much trouble. But it seems that one of the aptly sized filter caps (22000uF - 80 VDC) has indeed shorted...
