Marantz CD-63 Mk2 K.I. (Ken Ishiwata). Yest another video about yet another heavily modified unit

Many things were moded in this English made unit:
Clock with TENT Labs Xtal
Rubycon Black Gates capacitors "everywhere"
NJM-2114D op-amps replaced with LM-6172IN
Muting circuit on the output disabled
Headphone output disabled
Overall, in my opinion, it sounds superior to the standard Ken Ishiwata unit. Sound is more open, with better treble and more detail. Haven't listened to it other than on my workshop test bench system, so cannot really say any more on that..

[@jacintemunoz3301]

for the headphone output, the volume is on the remote control

[@hear-net-au]

Indeed it is. I forgot about it. Apologies

Ones agian Very nice boss ❤

2:13 is the reason why i hate modified stuff and don't touch them. Sooner or later that glue will let go and the board will short. It's not like they couldn't use proper standoffs and screws to mount it properly...and don't even start me on BG's, all can go to the bin.
This is yet another example of a unit modded by an audiofool...hope someone at least measured if those 100MHz op-amps they had put in it don't oscillate in UHF let alone someone actualy measured the jitter with the old vs new clock.

[@hear-net-au]

Never mind jitter. I will soon put a video where I have measured the frequency of the added "femto" clock, and it was floating more then the regular PLL 🙂

I'll buy those BGs from you.

No probs. Send me an email please.Details are in the channel's main page.

I'm being quoted 200-250 GBP to have the laser replaced in a CD-63 MKII KI Signature. Is this price expected? I'm not familiar with this. Thanks.

[@hear-net-au]

Rather pricey. They cost about 10 squid. The rest is labour. It takes less than an hour, but they might have a minimum of 1 hour.

[@edwardwoodward3471]

@@hear-net-au Thanks for the reply. Yeah I saw on ebay the lasers are cheap. £200 in labour fees is just too steep for an hours work.

[@hear-net-au]

@@edwardwoodward3471 These kind of charges usually mean that the workshop doesn't want to do that job and if you were to engage them anyway, they would've given it to someone else and just would add their margin. Anyway, lasers hardly ever fail in CD players and there's good chance the fault is elsewhere
