Yamaha CX-1 Preamplifier Repair and Restoration

After picking this preamp up this past week, I decided to open it up and take a look inside to see if it needed any servicing or repairs. Overall, it only needed a light amount of work. The typical issues were found, including bad solder joints and dirty potentiometers and switches.
I appreciate all of the feedback on my last couple of repair and restoration videos. I will continue to film more videos like these, as people seem to really enjoy them. I try to read and reply to most comments on my videos, but it takes a while because of my busy work schedule. Thanks!

so hifi connor, slap technique works wonders

[@williambbrayford408]

I love your work and have watched all your vids. Those Kenwood power units were great restoration vids and they sound fantastic with whatever you have driven them with. Cheers!

[@talathussainkhan9052]

I really like this preamp. It would probably work really well with the kenwood monoblocks. I'll keep an eye out for it. Nice work cleaning it all up.

Great vid man, love to see it. Looking forward for what's next in the pipeline...

[@PrimeHiFi]

Thanks dude!

[@technics-n-thuiast8346]

Always liked that preamp and the amp that went with it. A lot of people said they sound very neutral and warm

[@paulschreuder4211]

Nice to see more repair video's, love it!

[@PrimeHiFi]

Thank you! Glad you’re enjoying them!

[@lexvankooten1]

Great video! Question: What does the subsonic-filter exactly do??

[@buitenb]

Another great video , I could watch this kind of videos all day long.
Time for more subscribers!

[@PrimeHiFi]

Thank you! More to come soon.

[@jackflackatari]

How about you do a
Kenwood L-07C or L-07C II.
Would be a great Match for the L-07M Amps.

[@PrimeHiFi]

I will if and when I get the chance. Thanks!

Hey Connor! 👋🏻 This is the first chance I’ve had to sit and watch this video in peace. Another top job bro. Yamaha has some really decent kit. Especially from A decade or 5 ago. I know a lot of the modern stuff still has the pure direct switch. And they carried on with the vintage look even their as1100 up to the 3000 range is built like tanks and sounds fantastic with the right components & speakers In fact if my memory serves me correctly there is A YTuber called stereo police who has the as1100 amp and he loves it. I believe he said he would take it over much more higher priced items. All I know for certain is the Japanese know A thing or two about real HIFI. Anyway hope your well? Keep up the good work. Greetings from across the pond. 🇬🇧

[@PrimeHiFi]

Glad to hear you enjoyed it! And thank you! I am well; very busy with work, so I’m only able to work on audio equipment on the weekends. I should have a new video out soon! Cheers!

[@michaeljones19731]

@@PrimeHiFi I'll look forward to it Connor. Cheers Buddy. 👋🏻😀

[@leschwartz]

I am really impressed with how well you get the faceplates cleaned up - can you share some of those techniques?

[@PrimeHiFi]

Usually hot water with a mild detergent and microfiber cloth. If there are tough stains, I will use a small amount of Simichrome. Hope this helps!

[@webking185]

One of the best pre amps from Yamaha. Match with the MX1

[@outfield1988]

That’s fantastic

[@atelier_HiFi]

the 80s Yamaha process of soldering components on the board leave a lot to desire.

[@PrimeHiFi]

I agree, although most manufacturers suffered from the same crappy wave soldering.

[@williambbrayford408]

Thanks!

[@gordanbobanac9903]

Hi, a have same CX-1, and have problem, one canal don’t work, is that problem in volume potentiometer or something other?

[@johnbravo7542]

Great service/refresh video,out of curiosity what do you do for a living,I'm presuming you work in an electronics field?

[@PrimeHiFi]

Thank you! I am an aircraft technician full time, and work on audio equipment on the side / as a hobby.

[@sgredsch]

[@Krifmaz]

connor takes the l07 to frankenfest!!!!! yahhhh wooooh

[@chinmeysway]

[@samflynn8750]

Cool thanks

[@dennishill290]

Lucky You... wish I had that piece new....Yamaha...!

[@pumelo1]

For a natural sound I recommend the Yamaha AX-570, no preamplifier is necessary. Power 2x100watt RMS 8ohms.I have this beauty at home.😉

[@stels7776]

I like all how Made in Japan

[@heryoneheryone3664]

I have one, this great amp

[@01sapphireGTS]

[@educamillo323]

[@marcoantoniojoaquim1797]

Perfeito me de papai

[@samflynn8750]

Show some soldering

[@frank40m999]

Je hebt er weinig aan gedaan, dus reparatie en restauratie is een beetje overdreven

[@jerryandlisa27]

Do you do work for others?
