That high quality circuit board material is a glass-epoxy formulation known as FR-4. Thanks for the video.

Fernando, I had the Nakamichi ST7, CA7, PA7, Dragon, and OMS 7 (Klipshorn speakers) back in the mid 1980’s when I was stationed at the Naval Hospital in Okinawa. I earned the nick name “Nakamichi Man” and spent many hours demonstrating the equipment to officers and senior enlisted interested in audio. (I should have started up a club, save that for another story). The components are first class and I highly recommend anyone interested picking up the pre-amp and power amp together. The PA7 (covered in another Ski Fi video) is heavy but extremely good as a sonic pair with the CA7. I highly recommend using both in a system. I’m interested in the Ford Cosworth but I’ll let you work in some magic before negotiating an offer. As usual, an extremely interesting video and I look forward to the Just Arrived collection every Friday. Take care and thank you for the video.

thanks for sharing your experiences, so cool that you had the system in Okinawa. Yes the Cossie is getting some love but won’t be on sale for a long time. It’s been so hard to fine a good one in the states. Cheers

Nakamichi turned over-engineering into an art frm.

Man your consistent analytical approach is really valuable. You take advantage of video for teaching. The engineers would be proud. As would the designers.

I purchased my Nakamichi gear while in Yokota AB Japan from 89-93 at the Audio Photo as follows a PA7, CA5, Nakamichi Dragon Tape deck, (which I took back) and got the RX 505, OMS CD Player and a pair of JBL XPL 160's!

hope you still have it all.

I’m still using my Nakamichi 610 control preamplifier in my office system that I have kept from the late seventies and I love it. My Nakamichi 600 tape deck needs a service but I don’t trust anyone in Sydney to do the job correctly. It’s great to see the work you do on the vintage Nakamichi gear as it is well worth restoration and it all sounds pretty good for what it is, if your into hi-end vintage them the selected Nakamichi components are well worth the effort. Love your work at SkyFi Audio.

Thank you for an Amazing video!❤ This preamp stokes the hell out of me. What an Amazing piece of equipment! I have a special soft spot in my heart for late 80’s gear. I have fond memories of my late father and I going to mom & pop audio shops back in the late 80’s when he was in the market for a hi end cassette deck. Nakamichi was always a brand he got very excited about. ❤️

That’s a hell of a chassis on the preamp. Some of the best quality I’ve ever seen

Wow never expected to watch a video on a hifi shop and find a cossie up in the air in the middle of it. Looks like you've got some great stuff there and good luck getting the cossie back up and running, don't see many about these days. If I'm ever in the states i'll have to visit the shop.

Those filter caps are HUGE for the amps output. 66k UF of capacitance per channel is alot for putting out just 225 watts.

Nakamichi PA7 Amp просто монстр!

In the early 80's I bought a 530 receiver. Used it for 10 years until getting larger Magnepans requiring more power. It seemed to be really well made.

I have Nakamichi TA-2 Stasis receiver and it sounds so beautiful too.

There are so few great pre-amp manufacturers now. I can only think of Parasound, NAD, and Emotiva that produce units that don't cost as much as a ballistic missile submarine. Really wish Pioneer, Sony, and Yamaha would return to making pre-amps.

Thank Nelson Pass

Sadly, their OMS-7 CD player had a high failure laser rate. Almost all the units you see these days suffer from that. In addition, there wasn't a digital out so you can connect to an better external DAC. I still own the PA-7. I believe the 7 series was the last hurrah for Nak, unless you consider their 3 piece Dragon CD player & DAC combo. A much admired audio tour de force which sadly succumbed to the digital era. Have fond memories of my 2 680ZX, 1000ZXL and a couple of others. They were on top of the cassette medium.

There is an excellent interview with Nelson Pass done by Steve Guttenberg where Nelson discusses the PA 7. Nelson's takeaway, "Avoid the 7II and 7E."

I had a double blind listening test with friends between the Bryston 4B and the big Nak. Both were great, the 4B came on top.

I love my CA-7a preamp!

Impressive preamp. And really nice to get input from your partner there in the shop.

I'm still using the NAK CA-7 with a PA-5 power amplifier (100 watts/channel 0.1% THD 8 Ohms / 160 wpc into 4 Ohms). Still sound fantastic driving KEF C80 3 way speakers. I'm also using a NAK TA-4A Receiver with KEF C25 monitors for my home recording setup with a MOTU M4, MAC mini and DELL 4K monitor.

I love and hate this channel, great info and items the fact I can’t afford them really pissed me off, like the car side line 👍,

Now I need a new keyboard after drueling

Had both units way back and the kappa 9 i worked in Dubai and got this unit cheaper at that time all tax free as well the kappas.

wow, these must be rare, the first time I see them 👍🏻

Nakamichi made some awesome products over the years. I had a 680ZX cassette deck for 39 years. Never had a problem with it. It was sad to see them disappear. I wonder what happened. Perhaps they sold the name. I believe I have seen the Nakamichi name on some low cost products. Reminds me of when Arnie Nudell sold Infinity to Harmon. They went from speakers like the IRSv’s and IRS Betas to car speakers. Thanks Harmon😩

I'd love a PA-7 to pair with my CA-5. Also, it is strange when one piece in the line (in this case, the CA-7) seems to be built to another standard entirely. I have a set of late 70's Yamaha separates, and the tuner, a T-2 is just on another level from the rest. It's like an aluminum brick with the one piece solid top and side cover. The amp and pre, nothing too special.

I think you’ll find it’s ALLUMINIUM 😊

Not at all Alan. I mix them all the time, for example I use a tube pre to tame a bright speaker with a solid state amp.

What if someone use a tube active step up for mc( two boxes) and go in a preamp like this ( I mean mm solid state)? Do you lose somehow all the magic ? I have already spent 1k euro on it. Can someone explain it to me ? If Fernando is not an engineer, is one of the best retailer, and have a bunch of people for topology explanation I think …
