Owned the Cyrus CD8SE Mk2...Excellent sounding player, but the reliability was shocking...Sent off to the technicians on 3 occasions in the 2yrs that i owned it...from new !
Hi, do you still have the VS55?
I do still have it and have no plans to replace it
@@HiFi-DIY Hi, I have the VSI55 integrated amplifier, excellent amplifier. I don't know if you are familiar with electronics, I would like to know the anode voltage on the 2 phase shift valves, from the diagram there should be 225 volts but in my amp it is lower, can you check on yours??
@@robertogranata6931 check this out www.frihu.com/roehrenverstaerker/customize/audio-research-vs55/ It is in German but guess that translated in browser would work fine! The article is about mine (this the very amp I own)
@@HiFi-DIY Thanks for the information, but I meant if you are able to do this measurement on your amplifier.
I have had the original since the late 90s, but the tonearm was bad and I didn't use it for 20 years. I decided recently to revive it. I bought a new old stock 9cc carbon fibre tonearm, project bearing grease, belt, 15v power supply, and because of your video, the AT 6006R. Just finished setting it up today with a SoundSmith Otello cartridge and it works, looks and sounds great. Thanks.
Happy that inspired you!
HI! HAVE YOU FIXED IT?
@@crimsomglory yes was easy, a new t-joint and some pneumatic tubes less than 10euros an 10 minutes work!
@@HiFi-DIY is it a particular "pneumatic tube"?
No just some proper pneumatic tube, the T-joint is from Festo so I also used there tubes
Hello, i have a digitech valve fx and i have a display problem, i can see the letters but the blue backlight is not working anymore
@@mooserm2613 thats might be a problematical as the backlight is, as I remember, build into the display
@@HiFi-DIY do you know how to fix that issue?
No and I have sold my Digitech 2112.....
Tytyty
how about custom made wheels? ya know, something really useful
Nice speakers!! early '80s I'd say. Speakers on wheels - *wonderful*, now why they stopped doing that. Maybe manufacturers will get smart again (KEF)
Thanks for the video !! Keep them coming 😊
This looks promising. The half width reminds me of Cyrus. At this price level, it should offer I2S, though. Is the drive user replaceable? Good luck with your channel.
Dificult to clean the dust 😮😮
Your are absolutely right, so I made a simple dust cover, when I am not using the turntable protecting it from dust!
I notice the Headphone jack is recessed on this version . Is this normal for this version, as I have seen other 8000a with a Flush mount socket design
Well I had two 8000A and the headphone jack was the same on both units, but I never use the headphone jack so I did not pay much attention to it, sorry
What a blast from the past.
There's a lot to learn from the past when they still used their ears to create ........
The grill is not original ............the original was in one piece . I found a mint pair for a very fair price and enjoy these speakers a lot .......like Maria Callas singing in my room and wanting to give her kiss after she stopped singing ... This speaker was engineered to have a big sound in a typical small British living room .....and it works out well this way.........the model one is my preference compared to so called later upgrades..............;it plays music coherent and without any hugh end listening fatigue ...........the bass rolls off earlier than a bass reflex but being a sealed bass load it continues to go deepr than a BR........... The better the amp and source the more joy it rings to the soul of music. Do a good job restoring it ........beware of very expensive foil capacitors , they tend to break the musical balance of the speaker because they have different electric parameters , ESR and inductive as well as favouring too much detail out of balance with the music ..... This speaker was still build when engineers measured but also LISTENED to their baby... They are able to transfer you to a concert hall.........;in your own home.......not many actual ( even high definition ) speakers can do that .
Agreed the grill is not original, some previous owner have cut it down! What foil capacitors (brand/type/serie) did you use? The sound I amazing, however I will still remove some stuff....like the fuses and the protection circuit.
@@HiFi-DIY I leave the fuses with direct coupled amplifiers , unless they use OPT and or capacitive loading.........it's not worth the risk ! .one can use better fuses at the expense of byuing those The circuit /level/protecting ......;;;can be turned of with a switch....on/off . With film capacitors one will gain detail etc ...........BUT this speaker was VOICED with the original capacitors ........you will loose the voicing and the musical coherence of the speaker.........original components/capacitors /sets are available in the UK at Falcon Acoustics who still build the best version of the LS 3/5............they claim the same as I do . BUIT you can easily upgrade the wiring and the speaker post as well as resolder all solderpoints with good solder like AN or WBT silver ...NO ROHS SHJIT !!!! Curious about the follow up of your restoration .........beware of tutning this beautiful sounding speaker into an audiophile high end headache with listening fatigue instead of joy listening to music.. Have a nice day.
The drive is made by Teac, and costs 80 bucks.
Well, there are more than just a drive you need at good servo circuit, and it is always the combinations that makes the magic happen. I am very happy with the sonic performance of this transport.
Is there a missing segment ~07:12 just when you were removing that unit out?
Well there was no recording as I had to put down the camera
@@HiFi-DIY hello! where to buy this Sanyo Laser transport?
Hi, can you tell me where you inserted the trimmer and its value? A thousand thanks
R241 is parallel with R242, I replaced R241 with two 15K resistors and 20K linear pot so now R241 can go from 30K to 50K. + I added a 10ohm resister in all the cathode to messuage the current.
Also wat too small. I would bet my life that my 40 lbs pioneer elite transport is so much better.
Very ugly all the way around. This is sad
Do you think I can use this amp without the fan on the back when I leave it open? Will it overheat?
If you leave the top open I believe that it will have sufficient cooling if it is free standing (not on a rack), however I would have it under close observation to make sure it is OK!
In your opinion, how good is this preamp? I have the chace to get one for 280 dollars
It is fair and if you are DIY and can work safely around lethal voltages give it a try. But it is not build premium inside!
I have the 6000n For the price, I think it's a good purchase I bypass it's internal DAC and use my external DAC I don't mind using the Play Fi interface as I only use it for Qobuz
Perfect. I will do the same. How does it sound?
Great job! Thank you very much for the great explanation. I would ask a suggestion regarding power amps. I'm thinking about an acquisition and I don't know what could be better between a Marshall 9100 and a Mesa fifty fifty. You have tried both of them. What would you suggest? I search something to pair with a tube preamp that can play good also at low volume. Thank you in advance and go on with these very nice videos ;-l
Well I would go for the Fifty/Fifty it is easier to service and if you make a variable negative it is perfect. The Marshall is more "hard" If you want to go with low volumes I highly recumbent a loadbox, the sweetest drive sound comes from the output tubes driven into clipping.
Can you program tracks?
No, programming.
Nice cd-Drive, how does it sound? 👌
Well it track better than my Cyrus CD8 SE and sound better. Sounds to me that there is more air in the playback.
Who's buying the players like this CYRUS?!? - Ugly design, the remote control looks very cheap, CD-loader as in the car's CD-player, display looks like the same one in a children's TOYS and, finally, after pressing the push-button you hear a disgusting sound of "click" - as if a fat flea was cruched.
Well, there is one thing this do, that many good-looking CD do not do. And you must hear it to believe it, I used the digital output and compared it to AudioLab 8300CD (using the build in DAC of the 8300CD) and the difference was mind-blowing.
Sorry, but Philips, Sony and teac-tascam did this better 40 years ago!
The Italians know how to make a chassis.
Reviewed it 27/02/24. Very revealing of classical and acoustic material, with great separation and detail on cello, piano and guitar. I played Lutoslawski, Webern and Chinese Classical. When playing hip-hop (Masta Ace), the sampled bass was muddy on 'I Got Ta'..This track loops a James Brown original, on what can't have been great equipment..the vocals are good with the track illuminated by the insistent looping which the turntable doesn't miss. On such varied material, the turntable did well..a thumbs up!
Beautiful beast
Hello, I would like to connect my MacBook to my AudioLab8300CD : macbook : 3,5 mm jack male AudioLab8300CD : do i need 1 or 2 rca male cables? Thnx for your help
the 3,5mm output on a Macbook is analogue, you will need at digital audio output
Hi, Did you have to adjust the laser after fitting your new one?
no adjustments, just replaced the laser/drive unit
Nice , thank you . If you compare this to my Quicksilver V4 , mine has no circuit board, just hand solded wires.
The classical B&O AM1, now supported by Ib Lundgaard, Electronic instruments A/S Struer DK, is used for testing output of amplifiers, power measurements as well as low level.
inih radioh apaan tong ?
from google.translate I got from Indonesian: What kind of radio is this? This is not a radio it is a testing tool for professional use.
Det er ikke Band & Olufsen men "Bang og Olufsen"
Av, det gik vist for hurtigt......tak det er rettet!!
Hey there My one doesn’t even come to boot screen. Have you managed to find out what was the problem?
Yes, I found the issues. There was two. First I had a look at the ”large” Electrolytic capacitors where one looked bad. However I found that two of them had cold solder joints, but replaced them anyway as they were OLD. Then the lithium battery was faulty, and the battery holder needed some cleaning before inserting a new battery. Final point was a master reset and then all was fine!
Yeah, heat damage. That is always an issue. Another reason I am careful with tubes. Ceramic sockets slightly taken off the PCB board would have solved that issue.
Yes heat damage, seams to be a general issue with Audio innovation tube products.
Det bar dejli :-)
how can this be 1grand n half
The "extra magnet" is magnetic shielding for CRT's back when this sub was sold. I have a demo video on my channel. It's a very weak sub, by any standard. Suitable as a computer sub, that's about it.
It’s made by an amateur, it is not a serial unit.
There is nothing to know, it’s oooold technology, it can be a one of
You are being a bit kind in the assessment of this rat's nest.
Put it on a variable output isolation transformer and bring it up slowly while monitoring the plate voltage of the output tubes. Start with that. Check for excessive ripple on B+ lines.
Sold it did not have time for it. You are right about bringing it up with a variable output isolation transformer, that is what I always do.
I had one of these back in the late 90's that I paired with a Mesa Quad Preamp through a BBE 462 Sonic Maximizer. It to this day was the best sounding rig I've ever owned. I ended up letting go of it due to a ground loop problem I couldn't solve and traded them to a guy for 2 Marshall heads. One being a JCM800/2210 that I still own and love to this day. I do wish I had that rack unit back though. I keep toying with the idea of requiring both items but they have gotten astronomical in price. You never know though.
Excellent content. Looking forward to more clips on that project. I've just got my hands on the model, also from 1990, and the power pesistor you are pointing at in the video shows some damage (white powder coming out). If you were to replace it, what exactly would you choose?
Leave the cement resistors, I did not change them. I will soon upload my learning for repairing this amp.
Thank you so much. I've seen your explanation on that in Part II 👍.
Did you have to use new plastic plugs to reattach the circuit board? Mine seems to be for one time use only. How did you remove the ribbon cable? In my cd8x, which is slightly different, I could not get that cable off without fearing to break it.
Which tubes does it use?
