Noticed this (sold) listing the other day. I've been watching/collecting Nikko gear for a while now and have never come across this model -- I've also never seen the Alpha V amplifier. Anyone familiar with this? Are these as thin on the ground as they seem?
I will also add that the images from the listing differ from the Beta V brochure photos I've seen on the 'net. The eBay unit looks to be 1U (note it only has 1 rackmount bolt hole per side) which differs from both the promotional photos and every other Nikko Professional Series pre-amp I can recall seeing. The faceplate also looks to attach with fasteners rather than by hidden collars under certain knobs. Curious.
 
Hi acy76,
I was the lucky guy who could not sleep one night, saw the new listing with buy it now, and was able to bring the V home. Its like the vintage audio lottery...! I have looked for more than a decade closer to 20 years just for a listing to have a chance at one.
My first Nikko was in '74-5. A STA6060. I traded it for a TRM-800 in 1977 at the distributor I worked at. We rep'ed the line. I still have the 1978 little Nikko book the ABG series was listed. My first Alpha came to me about 15 years agp, and I have collected, turned over and loved a lot of the rack series. All the time dreaming of an opportunity for a V.
I also picked up a Gamma V this year.
So, to your musings about pictures etc.
The Ebay listing is the real unit. Btw, it is Serial #00002.
It is thinner by 1/2" than all the other preamps. I currenty have a Beta I, II, 40 and 50II. Had the 20 and 30 once too.
The V is a one lug mount, not 2 like the rest. It is as deep as wide. The body is...unlike the rest. Lots of pieces and screws. My understanding is these were hand assembled. I believe it. The circuit board soldering looks it.
The board is also in upside down. yes, the board rests at the top of the unit, the componants facing down.
The top is a solid panel, the bottem is vented. Weird, but venting the top would be disasterous is something metalic fell in. It is not obvious in the little Nikko books, but the phono section has 3 "channels". For 3 tables. Ch1 has the 5 resistance setting switch on front, all 3 have capacitance switches on rear. All RCA are gold. Aux, tape, outputs.
Oh, and no tone controls. No loudness switch. Signal in, signal out. It sounds just like that.
If you google a Nikko c-201 PRO, you will find the Japanese domestic version. Is silver/chrome. Where you noted the little bolts on the front on Ebay, the C-201 has small handles. The C-201 also has a finished one piece cover folded over the sides like all the rest of the ABG line.
Pictures.... Yes in due course. I have given the controls a first cleaning. It works 90% of the time at the moment. Still a contact, or the relay, cutting out some. I will re cap.
I have never found another piece of info on it. No manuals, schematics. You will note I have reached out to the other 2 old posts to those who had actually worked for Nikko back then.
Sure would be fun to know how serial #2 came to North America. Sold to the first customers, or an office demo for Nikko in N.Y. Or L.A., or a store demo show piece....$750 USD then, is about $3000.+ now.
IF ANYONE KNOWS THE SOURCE OF A MANUAL! Please let me know!
More later.

Congrats on finding this unit. Will be nice to see some nudes. The Yamaha C4 is similar, solder side of the circuit board is on top and removing the three sided top reveals just the board solder joints.

Look at that phono switch settings. Phono 3 has an impedance switch on back, not another capacitance switch. It also has a low impedance of 600, maybe able to handle an MC cartridge which is not susceptible to changes in capacitance and not needed on an MC input.

Interesting preamp. Enjoy. I look forward to you starting your very own thread about this unit and posting some drag and drop pictures of the unit.
