1983 Philips CD100 CD player repair
 

Hello again,

This Philips CD100, apart from bits and pieces, was the only thing I bought at the Tonbridge Audiojumble yesterday. I paid £60 for it and cosmetically it is in mint condition and complete with box but I was told that it wasn't working except that its laser was OK - they usually are on these Philips first generation machines, and this one has an early CDM0 transport.

I got it home, switched it on and attempted to play a disc and the disk hardly moved - it obviously hadn't been used for a very long time so probably the lubrication in the motor had dried up and/or its power supply was poor. I persisted, kept pressing play and eventually it managed to read the TOC but wouldn't navigate past the first track and there was no audio. There was a knocking noise coming from the transport as well which was worrying ....

I took the case off and cleaned all the connectors, retried it and away she went, still knocking but the audio was working OK on both channels and it was now navigating to all tracks, it even played all 15 test tracks on my Burosch test disc and not many machines achieve that. I checked the power supply at the five voltage regulators and four tested OK, but the one on the -3 (DAC) rail was reading very low, with less than -18v input, -31v is the correct voltage. There are a couple of 100uf capacitors in the circuit prior to this regulator so I took the machine over to Ron Bryan to fit a couple of new ones, one was still OK but it was replaced anyway, the second was knackered measuring only 6uf. The input voltage at the -3 rail voltage regulator was rechecked afterwards and it measured just over -31v.

I brought it back home and set about fixing the knocking noise coming from the transport which could have either been a noisy servo or something wrong with the magnetic clamp in the lid. I removed the clamp from the lid and placed it directly on top of a disc, played it and the knocking had gone. Also in the lid was a long flat spring, so I checked its position in the exploded cabinet diagram to find that an accompanying part was missing. There was also a note in the diagram stating that both parts were deleted from later models so I reassembled the lid without the spring, played a disc and it was silent at last. Obviously this spring had proved troublesome so Philips had stopped fitting it.

This CD100 is the nicest one I've seen, it is an early example as it has a Philips bodge inside consisting of an extra PCB with a couple of extra chips on it but it works very well and sounds superb.

Does this one have the Sony chipset or the Philips? I thought the one with the piggyback chip was the Sony type but after all this time I may have that the wrong way round;D. They sound great and there are a suprising number still about.

Hello Richard,

This one has the Philips chipset, you can see the Philips logos on the chips in the pics below. You can also see the extra PCB tacked onto the top of the board in the second pic, which is much tidier done than the 'fix' seen in the other CD100 we did.

There are indeed a few of these still around, not surprising as mechanically they are second to none in build quality. Nice Philips CD100s and Marantz CD63s always get snapped up for good prices on ebay and there's one German vintage hi-fi website selling CD100s for €800 - €1000 apiece !

Here's the circuit diagram for the CD100 / CD63 power supply (and probably all Philips first generation CD players) showing all the voltages on the regulators. The voltage regulator reference and pin numbers are printed on the back of the lower PCB which can be viewed after removal of the bottom covers.

Certainly remember doing those way back and being on the Philips course in Glasgow which I think was in the Excelsior Hotel. The CD104 was an excellent m/c too and had very nice build quality with just one or two stock faults which usually was the feed through soldered joints on the PCB.
The early Sony CDP-101 was also a remarkable m/c and lasted very well but perhaps not a long as the Philips offerings.
Nice CD Howard!

Re: 1983 Philips CD100 CD player repair
 

Oh I love the Philips 101. My brother had one back in the early/mid 80's and then moved on to the 104. Both really nice designs. At the time, we were flogging the Sony 101 and that was great too - a very sturdy, solid design with a seperate chucking motor IIRC.
At the time I had a Marantz CD54 which suffered from a recurring problem of 'not reading'. A twist of the chassis would put it right, but I never did track it down.

Re: 1983 Philips CD100 CD player repair
 

Ha Ha! Officially it wasn't a 'bodge'. It was an 'Interim circuit change' or 'Official Circuit Change' pending modified boards and/or chips becoming available. TS (Technical Support) department would have been most upset if it had been referred to as a 'bodge';D

Re: 1983 Philips CD100 CD player repair
 

I have the CD63B Marantz version of the Philips CD101 - no 'Interim circuit changes' in that one, Philips had sorted out their chipsets by the time they were built - and apart from cosmetic facelift changes and the CDM1 transport they're exactly the same as the CD100.

I have a couple of the next generation Philips CD104s and the Mission DAD7000 variants and also the Marantz CD54 which is virtually the same machine but built in Japan. They are all well built but the Marantz CD54 stands out as it is totally original and works perfectly, no doubt due to it not having those troublesome griplets in its PCBs. These later models have now become very collectable as well.

I have a Sony CDP101 but that has packed up :(

Re: 1983 Philips CD100 CD player repair
 

I bought a Sony CDP 101 new when they first came out. Was posted to Ascension Island when I had a problem with it. Skipped it in favour of a new model from the states...Wish I'd have kept it...

I have a working Sony CDP-101 now, it has had both its troublesome Sanyo STK6922 motor driver chips replaced with the more reliable Sony BX1201 chips and its drawer mechanism has been regreased so it should be OK.

Comparing it with the Philips CD100, build quality is just as good, ergonomically with its remote control, soft touch controls, random access and digital display it is superior, but sound quality wise the Philips is a much nicer sounding machine and that IMHO is what really counts.

Re: 1983 Philips CD100 CD player repair
 

This thread had me reaching for my Marantz CD63B purchased new in 1983 and in regular use for about 7 years until I could no longer resist the lure of a remote controlled model.

I gave it a good dusting down and popped in a CD flooding the room with music then noticing it actually said Marantz CD63 not CD63B on the top I wondered if despite the handbook which I still have being for a 63B I'd actually been sold a 63 so switched it off and turned it over to find a sticky label designating it a 63B.

All well and good then to my astonishment I noticed I had never removed the two transit screws despite them having clear labels under the screw heads and a clear instruction in the manual so this is one man who has to confess to not always reading instructions!!

Friends and colleagues in the broadcasting sphere used to marvel at the sound coming from it playing through a Quad 44/404 MkII and a pair of Celestion SL6s so would there have been any discernible sonic difference had the screws been removed?

I left them in place for today's quick test and these days my ears aren't what they were so I doubt I could have detected any subtle changes :(

Hello Alvin,

I've got a Marantz CD63B as well, it's the same as the Philips CD100 with the facelift case of the Philips CD101, in black. The CD63B model was built for the Japanese market (as marked on the label), the earlier CD63B with the CD100 case was dark grey in colour and was never sold here. A few of the later models were sold in the UK, maybe because they weren't selling well in Japan.

The transit screws screw into the chassis of the rubber mounted CD mechanism to stop it from bouncing around in transit, in the case of the top loading CD63B I would imagine that the only effect would be to impair its resistance to shock, but in the case of the front loading models like the Marantz CD73 they also prevent the tray from opening. Sound quality shouldn't have been affected.

Howard :)

Re: 1983 Philips CD100 CD player repair
 

There are quite a few cosmetic differences between that CD63B and my CD63, most notably the different LEDs, as well as the different printed graphics, lid design and case colour. Personally I think mine looks much better, but then I'm biased :)

Re: 1983 Philips CD100 CD player repair
 

I like the champagne gold CD63 too but I don't have one yet.

To complete the CD100 variants, here is a pic of the early CD100 sold in Japan as the Marantz CD63B in a dark grey case ....

and lastly the US market Magnavox FD-1000 ....

Re: 1983 Philips CD100 CD player repair
 

and like my example the designation on the top of the deck is CD63 not CD63B.

Hey thanks for the hot tip, Howard! Apart from otherwise being in excellent condition my one pound bargain car boot sale CD100 was also knocking and googling threw up another forum's q & a attributing the noise to faulty bearings supposedly sealed for life and therefore not curable but on reading your post I removed the spring you mentioned - like yours no sign of an accompanying part - and hey presto it now runs very sweetly.

Thanks again,

Alvin

Re: 1983 Philips CD100 CD player repair
 

I'm reviving this thread as I have a tale to tell.

This morning was my weekly fleamarket visit. By 1pm most sellers were clearing up. I noticed a CD100 with an ITT casseiver on the ground near a stall. Then, the owner suddenly put his foot upon the receiver and was clearly about to kick it down the road! I daresay the CD100 would have been next.

At this, I went over and asked him how much for the two. After some haggling I walked away with the two for 5€!

Got them home and before doing anything else I cleaned the optics on the CD100. Plugged in and tried a CD. Worked first time! :thumbsup: I 'm especially blown away by the low end.

I'm still sort of in a daze over this, hate to imagine the fate of this gear had I arrived a few seconds later - destined to be trashed in a rain sodden back street (that sounds a bit like a typical saturday night out here!;D )

One thing I can't quite work out is the front LED display, a user manual would be useful if anyone has a scan they wouldn't mind posting here or emailing... presumably the upper one ('Progr') is the TOC/total tracks and the lower, the one currently playing?

Re: 1983 Philips CD100 CD player repair
 

Tremendous find.
The bottom line of LEDs shows the track being played. The upper line gives a basic programming facility. If you want the CD to start on track 4, press the Select button 4 times then press Play. If you want to play tracks 4 and 6 press Select 4 times then press Store, press Select 2 times and press Store, then press Play. You'll soon get the hang of it. This obviously only works for the first 15 tracks on the CD - after that all you can do is play the tracks sequentially.

Re: 1983 Philips CD100 CD player repair
 

Oh despite getting the ITT cassiever thrown in that does sound a tad expensive to me considering my CD100 only cost me one pound :-D

Seriously though well done Ben on getting such a bargain - as I've mentioned before I found mine lying in the dirt at a car boot market and the seller not knowing what it was only asked 2 quid for it but I felt duty bound to haggle the price down by half........

Re: 1983 Philips CD100 CD player repair
 

Thanks for the info Paul. This deck's LED display reminds me of what was up to now my earliest CD player - a DUAL CD-120 front loader which I've also seen badged Thomson. that unit also has a VFD in addition to the LEDs. I will have to overhaul it one of these days.

And Alvin you're right mine was pricey compared to yours! However, the guy asked 20€ at first... So, after my kindly pointing out that two minutes earlier he'd been about to trash it, I had a strong position in the bargaining ;-)
