Who is to be the hero to create a wiki about the DIYAUDIO Shigaclone thread. I'm not up to the task but there are people here who is.

Another shigaclone in the works here...

I was able to snatch one of the last RC-EZ51's in the UK it seems, many thanks go to J. Baldham for helping out!
Now it is up and running with the first mods... more are to come. C906 is an MKP from RS and will be replaced at
some point. I was close to a heart attack when I lost a solder tab underneath C906 (too much wiggeling on the wire
that connects to the MKP) but was able to fix it with some magnifying glass surgery
I am planning to power the 5V section with a Paul Hynes 3Terminal replacement reg (with rectification and filtering in
front of course) and will do as per the picture in the thread. There is however another pic in the Okapi pdf that shows
a wire jumper (5A to 5B) on the backside of the board. What's the reason for this jumper?

Hi,
glad to be of help.
Good to see yours up and running.
I have had a few problems with lifting tracks, so much so that I've abandoned mine feeling that it is too delicate.


Looking at the board in the pic mine did exactly the same except when I did another swap the leg fell off the chip DOH!
Gone off on a modding Philips cd40 spree.

Here is a little ad.

Found several boombox CD mechanism. No display, no remote and no keypad.

Just CD laser head and controller PCB.

$20 for one. Used.

I could replace it with new CD head and it would be $30 for one CD mechanism.

Send me PM if you are interested.

If there is enough interest I may redesign the board with all Shigaclone modifications already included.
I wonder is this Sanyo transport is still available as a separate unit and if LA9242M and LC78601RE can be purchased in small quantities.

MCD-S925F
MCD-ZX 600F
MCD-ZX 100F
MCD-ZX 200F
MCD-ZX 250F
MCD-ZX 270M
MCD-ZX 300F
MCD-ZX 310F


So far from above list I can confirm that MCD-ZX 200F use same cipset as RC-EZ51 and MCD-ZX 250F.
http://vicol-audio.ro/docs/sanyo_mcd-zx200f_sm.pdf

Also MCD-ZX 500F MCD-ZX 550F make use of the same CD mechanism and quite similar DSP cipset LC78602RE instead LC78601RE.

I have done some research into this a few months ago. LA9242M is available in UK: Sony LA9242M IC Sony | BuySpares UK

LC7860xRE seems to be only available from random Hong-Kong/China suppliers. Seeing as the UK price of the LA9242M is ridiculously high, it is probably best ordered from China as well.

I would be prepared to invest a modest sum of money into this (maybe £100-200). Shigaclone is my pet project, and I utterly hated having to turn down people who wanted to buy JVCs from me recently. Besides, I distributed all the CD mechs I had among fellow forumers, and left only one for myself, so (obviously) I would like to have a spare for experimenting...
