I search for Technics/Panasonic datasheets

philbyx · 2nd April 2004, 06:20 AM

Hello

I have a CD player Technics SL-P333.
It's marked 4 dac 18 bits on the face...

In it the components I found are :

a mn1554 (in the part called "digital" on the PCB)...
a mn6625 connected to a memory 2k x 8bits CXK5816 sony (in the part called "Micom" on the PCB)
un mn6623, printed "mash" on it (in the part called "Audio" on the PCB).

Then some op amp :

4558, 4560, lm833

I would like to find the datasheets for the "mn" circuits, or better, find the schematic diagram of the cd player (or one of this generation)...
It is to change the op amps, but I would like to know who do what...

Thanks
Philippe

Here is something.
I'll have a look at the rest later this afternoon

MN1554: 4 Bit µComp, 4kBit ROM, 256x4 Bit RAM
4558: BCD-to-7-Segment Decoder
Could be NE4558 also so Google will help you here.
4560: 4-bit BCD Adder
LM833: Dual, lo-noise, ±18V, -40..+105°
Do a Google search for the datasheet.
MN6623: no data

It’s not a lot, but that’s what I found

If you really want to tweak I would consider asking the schematic from Panasonic.

Thank you very much Hugo.
I saw your scan about the MN6623. I am looking for the DAC, which is the MN6625 (a MASH one), but I can't find anything...

4 years have passed, and no datasheet on the net.

Any of you ever got it?

Hi,

I have Service Manual for SL-P202A which is LE model of that genaration (1989). If someone is interested in send email.

I'm interested if someone moded any Technics model from that generation (202, 212, 222 or 333) and what were results?

Regards,
I.
