this is a standard plug you should be able to get from radio shack or other electronic stores. just take a picture of where the connection is on the unit with your mobile phone and show it to the sales person. cheers, mark

yes they need unsoldering from the board and new replaced if needed but you should be able to solder the ones that are already there just check for loose connection on them

SOURCE: i bought this CD player in 1989 and all of a

these models use the 12.1 philips laser mechanism and your right it is a very common problem.
various marantz / philips / cyrus cd players etc also use it and are plagued with the same fault.
it's a 90% chance the laser is dead!
philips realised the unreliability of this laser and uprated it to the identical looking VAM-12.
do not dismiss the spindle motor as these also fail quite alot on this mechanism.

hope this helps.

The reverb quit working on my envoy 110


This issue could be a cracked solder joint on the reverb circuitry or because of the opamp driver in the same circuit, let me know further.

I have almost completed a diy modification of a Marantz CD67 Mkll OSE cd player. When I connect earphones the machine plays beautifully. However, when connecting the analogue audio output, sound is only...

I dont know what all modifications you have done but here are some tweaks that would be good:

IMO the tweak steps that should be made and order I suggest is good would be following

1) eliminate the output electrolytic caps from analog output (C656, C658, C655, C657)

I have replaced them with wire jumpers. It would be wise to check the DC component at output connector with multimeter. In my experience it's never more than abou +/- 20mV, which is mostly of no concern. Only if you have a true direct coupled amp where there are no caps in signal line it might happen that the DC component will also be amplified and sent to speakers. I think there is no commercial amp built this way, but some DIY projects might be.

2) Change the opamps. National LM6172 seems to be the most popular candidate and is the one I'm using.

Here the most important is to make sure you will place the additional decoupling caps to the supplies of opamp as close to pins as possible. I have 0.1uF polyprop caps from pins 4 and 8 to ground. When choosing the caps go for the ones that have as small dimensions as possible and as short legs as possible. Also place a cap on top of the opamp between +/- pins (pins 4 and 8). The value of this cap is not critical. Here you should pick some sort of SMD cap with as big capacitance as possible. I used some that were soldered off of some scrapped Intel PC motherboards. It is (at least I think so) non polar cap and the DMM measured it 20uF !!! I don't know if its right but it fits well on top of SMD opamps (I didn't get DIP cases from RS for some reason, even though the part nr. was right). A good place to look for ideas about opamps and decoupling is audioasylum forum.

3)Modify the clock. Install a sepparate one or use the description on site. I did my clock mod very sililar to that independently and as it turns out the techical solutions were similar and also our findings about changes in sound...

4)Better decoupling to supply lines. Use your imagination here.... One warning though, I once decided to change almost all the el. caps in the player for better ones (Nichicon xx, I don't remember the series at the moment). So, I replaced them and to some places I just put bigger values than stock. Well as it turned out I managed to overtweak a bit and now it takes about 30 sec before the display lights up :) I have studied it a bit, also with scope but can't fiqure out what causes the delay. Player starts normally and other than that there is no problem... so I have accepted it as just one more little thing that makes my player special.

Faint & distorted audio on am sw & air

When I bought mine, I too thought it had no audio, until I opened the user's manual and read about the initial setup. After performing the steps described in the manual the sound came as if by magic.

Is there a way to make the sound of the reverb on my deville 2-12 sound better ?

modding the reverb takes some electronics experience...if you know where the reverb circuit is. all you can really do is change the input caps that make the tone bright or dull... larger uf for dull... lower cap values for bright... it's in the signal circuits... dont mess with power caps. The schematic shows op amp into the tank and out of the tank to another op amp...Output of the tank to opamp.. Id double that input cap ( 330 pf ) to see if you get more response into the opamp... then look at the circuit C17-C18/R33-R34 894cf4a0-46f7-4f21-9667-be620f05b31d.png

My ps2 dvd has picture but no audio

Checck the cables , check the input, if both seems Ok , then the preamp output or the audio processing(D/A convertor ) is faulty or the opamp at the output is faulty. check with a test audio signal

No power in my altec lansing S100 121i 2.1 speakers

troubleshoot the transformer and try to replace the Opamp (UTC458) on the circuit board. the Opamp might be broken and shorting the circuit and fry your transformer. goodluck.

I have a Denon 1650 CD player. Denon doesn't carry the parts to repair it. (Scratchy sound on all CD's). Are there aftermarket parts anywhere? Thanks Ray Durr

Based upon your description, the problem is most likely either the D/A converter IC or a bad audio output transistor/opamp. Without seeing the unit, remote diagnosis is just a guess. The IC should be available generically. Can you post a photo of the board? If I can see what is in there, I can point you to the suspect parts. I don't have a service manual for this one.
