Absolutely great stuff.. Replacing caps with ELNA Audio Grade caps or Nichicon are by far the finest Capacitor brands out their. My 14 year old Marantz SA-15S1 CD/SACD Player is absolutely loaded to the teeth with ELNA Audio Grade caps and that's why is still going strong all these years later. My beloved Denon AV-4803 AMP also 13 years old is loaded with both ELNA Audio Grade caps & Nichicon caps. 🤓👍
Thoroughly enjoy watching your refurb clips, watching equipment reviews pale in comparison. The internals of this player make my YBA CD100 look sparse in comparison! I’ve been mulling over buying a Krell integrated online but reluctant when you can’t see and hear what you’re buying in the flesh.. and in my mind at least I can’t imagine couriers taking too much notice of ‘FRAGILE CONTENTS’ stamped all over the carton. Keep up the good work. Thanks for sharing.
Hi Tony, thanks and yes the courier factor is one that must be seriously considered. I use fully insured shipping via Pack and Send for all my business freight. That way if anything happens, its covered!
Good video. The U7 and U8 mounted at the bottom psu board is probably relocated there to make sure they thermally track well and not change temps due to convection. I remember (probably it was) the Naim NAP200 with two transistors mounted at the bottom of the board where the air is still and would stay at their operating temperature.
Great refurbish Mike. Love your videos.. 👍 maybe some day you can tell us more about problem pcbs with throug holes wich need pre heating and wich can easily damage 😂 Greetings from the netherlands ..
I have one KAV-300cd has the same issue which happened yesterday. What was the main problem for it? Did you replace power transistor of power supply board?
I've worked on many of these so I don't recall the exact details with this one without looking at my database/invoices. With anything like this, I recommend a visit to your local specialist. Parts should not be replaced unless they need to be, determined via testing.
Hi LA. You do nice work. Thank you for making & posting this video. (That Krell CD player is very nice). Thank you again for sharing. God[Bible] Bless.
@@dennisbragg8648 No problem, I'd contact Krell service in the USA and ask who they recommend in Vancouver. Alternatively, contact the best hi-fi store/s in Vancouver (I've been to a couple, can't recall the names) and ask who they use for work like this.
In most cases, I'd suggest visiting a specialist repairer for an accurate diagnosis and repair. Every case is unique and I would need to inspect and test your unit to diagnose the issue/s and determine the work needed to rectify them.
Find it interesting that Krell uses MPSA92 for audio output. Because as I understand that'a a high voltage switching transistor. I know this device, because I've used them as the display drivers in a nixie tube clock I built a while back. I've also seen MPSA92 been used for line switching and pulse dialing in telecommunications equiment, again for switching high voltages. So it's not really the first device I'd think of for HiFi audio signal uses.
Great comment, interestingly MPSA92/42 are used in a lot of really great hi-fi gear, Krell, Levinson, Perreaux and many more. Really robust devices, high voltage as you note, great parts, I keep a ton in stock for this reason.

could anyone help me. i need a puck/ cd clamp for a krell dsp cd its got a phillips cdm1 mk11 transport i would consider a replacement part or original thanks
Great video. Did you test those tantalum caps on the DAC board? I find lots of out of spec tants when working on old kit like this. In some cases it's best to replace with non tants, just have to be careful not to put too low an ESR part on some regulators as they don't like it.👍
Hi Ian, yes I tested these tants and they were all good. I prefer to replace them with tants, where needed, tants have generally superior HF ESR and were originally selected for this reason in many applications as opposed to the high C/V which many assume is the reason.
Wish we had a technician that takes the care you do in New Zealand ... Love ya work ... 😎
You're too kind!

Incredible the amount of components and build quality.
Nice vid Mike. Enjoyed the croaking frogs in the background too. Looking forward to your next video👍👍
Always a pleasure to watch your videos.

Hope to watch some videos of esoteric players from you. 👍
My unit still has power on, screen display well. Press open button still hear tray motor sounding. Hope I can fix it when I back home
That sounds more positive, likely a mechanical issue, deep service needed.
Excellent video,,awesome gear,,,,from when gear was awesome...
Great video was just looking at getting a kav 250 .
I send you an email about the Rega transport:)
What is the best krell series 🤔 to you?
I really like the early KSA amplifier series, fan and convection cooled. I also really like the PAM preamplifiers, just beautiful.

Are those damping pads on the chassis sides?

Lovely work you should’ve fixed the bad work that was done by crown of lol it’s not often found I was surprised
Do you happen to have belt dimensions on this unit? Got a simuliar vrds-7 based unit thats missing a belt. Thanks
Any tips on buttons not working? Clicks but no response.
The best advice I can give most people in cases like this is to find a really good repairer familiar with the equipment. Where are you located?
Thx. Vancouver Canada.

Thx so much
What was initially wrong with the player?
From memory this one had a power supply fault rendering the player useless. More details via the article on my website, linked in the description.
Hello I like your video thank you
Hi, how do I fix the CD Transport which is not working in KAV-300cd

Who makes stuff like this any more ? Would cost a fortune to build to this quality

Lol
Krell kludge.
