The CD Transport

[Peter Daniel]

BTW, regarding clocked output circuit in post#12, the MCK-EX connects to a pad were original resonator was installed. It would be the pad that connects to pin 61 of LC78601 (XIN according to datasheet here: LC78601E datasheet pdf datenblatt - Sanyo Semicon Device - Compact Disc Player DSP with Built-in Microcontroller ::: ALLDATASHEET ::: )

Peter, beautiful work as always. Wish I could find somewhere to pick up one of these old JVC boxes!!

 

[RAYSIMMONS]

Same here, those jvc boom boxes are impossible to find.

Here you are: http://www.visions.ca/catalogue/category/Details.aspx?categoryId=79&productId=601

Thanks Peter, the price is right too, unfortunately they will not ship outside Canada.

As usual Peter very nice work. The only snag for me here is the SC944. If my memory serves (and it may not) doesn't Scientific Conversion want a minimum order of 10 or something like that?

Regards,
Dan

Is there an alternate ?

Several JVC players look similar.

It doesn't need to be SC, you can use any other transformer. For instance: Digi-Key - 470-1003-ND (Manufacturer - S22083)

Which Dale



Peter, which are the Dales you have on your boards?

I find these on Farnels catalogue and they have quite a different aspect.
Sorry for the bother.

 

[Peter Daniel]

I think those are RN55

Hi Peter,

where do you get those washers, are they from mcmaster ?

 

[Peter Daniel]

Those are commonly used in aircraft industry, I'm not familiar with any retailer that sells them. If mcmaster don't have them, I don't know who else would.

 

[etoiledusoir]

Hi Peter,
I have another question, what is the value of the resistor on the display board.

 

[Peter Daniel]

I'm using 10k

What is the CD holder made of? What actions are necessary to put on and take off the CD? Is it modified from the original?

 

[Peter Daniel]

You mean the clamp? It's taken out of the boombox.

It works exactly same way as analog turntable: lift the (magnetic) clamp, change the disc, put the clamp back on.

Setting a new book mark here... Great summary report Peter! MUCH easier than the three-day epic I went through for the first one!

Thanks!

Now comes the PS part.

48VA Hammond transformer (166L24) fits perfectly in a Hammond 1590T enclosure. The diodes are mounted directly to connector socket and the whole thing came out quite elegant and simple.

Is it safe to leave those msr860 floating around in there? The backs of them are connected to the output pin. Did you insulate them?

 

[Peter Daniel]

The don't touch anything, so I don't insulate them.
