Re: Re: Re: Another CD63KI
Hi.
Well after letting the player settle for over a week on continuous repeat the player has taken on a whole new lease of life 😎
When I first installed the Zapfilter 2 output stage the player sounded ultra detailed but uninvolving. Now it still has all the micro detail as before but the whole sound has opened up, the sound stage is huge and vocals sound as if they are in the room!
Next step is to mount the Zapfilters PSU in a separate enclosure and add another transformer for the servo regs
The only problem I now have is yet another dodgy laser from Grandata
Cheers,
Mags.

Ahh, good old Grandata. Great news otherwise though Mags! A dedicated transformer for the servo regs is on my to-do-list too, so I'll wait with baited breath for the outcome.

Excellent news. It always takes a while for mods to settle in. Also do you leave the cdp switched on 24-7 as this makes a huge difference.

Hi Brent.
When I used to mod these players for other people I never had a problem with Grandata but the last 2 laser I've got form them seem to have a different Vam1202 sticker on them? Luckily I have a spare CD63KI and CD67SE (slightly modded) with good CDM12.1 lasers and a VAM1202 from Dalbani. The 1 in my player jumps even on new disc's and will not read CDR's
Cheers,
Mags.

Do you miss it? Is that why you planted the virus that would stop it working with the lid on and then eventually just give up for no apparent reason and with not even being breathed near?
I have a special player indeed. It goes to school in a Fiat Doblo.

Too much magnetic flux poisoning the area ?
Haha, quite! Seems to be some kind of problem with the logic chip. Everything else has been replaced anyway! I'll be checking all the voltages tonight and seeing if something's recently gone awry.
Thanks for your kind offer Ray. This project is on the fourth position in my to-do list, after a Low Noise compact PSU for the discrete out, followed by some Thermoni(a)c Needs and a couple of minor adjustments to the line conditioner / balanced power source.6h5c said:
Has anyone an alternative for the now obsolete Panasonic HFQ series 120uF/25V capacitors as their impedance at 100kHz is 0.200 ohm while the newer FC-series is 0.250 ohm. ??
Have you tried resoldering all the pins? These big(ger) ICs sometimes suffer from bad solder connections. Be aware of electrostatic discharge though!SimontY said:
Hmmmm, seem to be some clock products on Ebay:
C1 clock on Ebay
D1 divide circuit on Ebay
These are rather good so I'm happy to recommend them. I don't think there's anything even nearly as cheap around.
The C1 seems to compare well against the old Audiocom DVC-1 (was £100 about 5 years ago). My DVC-1 went faulty (like most things I touch) so I replaced it and the divide by 2 circuit with two C1s. This arrangement (one clock purely on servo) is much better, allowing many more fine details out.

Seems that way. Bad QC.
Brent's old trick of adjusting the glued bolts on the underside was necessary for my VAM1202 to play CDRs. Maybe it's to do with disc thickness which may affect focussing, but my blanks are mainly Plextor made by Taiyo Yuden which are supposed to be the best.
Adjust too far and it stops playing some normal discs!
The art is to find the sweet spot where it plays everything.
I had a couple of especially tricky CDRs and one tricky normal CD that provided the boundaries. At the sweet spot it plays everything.
I found that adjustment to one of the bolts was not sufficient and I had to adjust them both.
Major pain but once done it has been playing fine for months.
Before mine stopped working again it would play everything (with no skipping or any faults) except Jazz at the Pawn Shop, which it didn't read at all!
Jizz at the Porn Shop? 😱
Oh, sorry, my eyes aren't what they used to be. 😀
I should point out that when I say 'play' what I really mean is the track-to-track, er, tracking which was the problem. If you just played rather than skipping tracks it was always fine. Just to clarify.

lol, it's not the first time that "mistake" has been made... The sound will make you jizm....
