ccschua,
thanx for the update. keep us posted!

If u live near wangsa maju there is one there same color as chua's and a slightly higher model EZ33, the EZ31 is about RM180+, just helping out

Mention it here, the unit will be gone!

one more thing, dont know id this model can be use or not, but there is a ez33 at norman harvey the curve..and ez33 at wangsa maju is rm208 if i remember correctly

thanx for the info mm.. weekend 'project'

i can ask if they still have stock at jusco is any one is interested...but only one color available... "Smurf Edition"... hahaaa

It doesn't matter what colour right? It's the innards that we're after!

oit dont play play jazzy...u may end up with innards that work like cartoon..hahaaa

you may have a point...

I have finally got it opened. apparently the components used inside the player is quite good. smells new.

Added schematic and service manual of JVC in open post #1.

ccschua,
looks like you're gonna be busy eh?
Would appreciate if you could document the steps that you took during the modifications, pictures(lots of it) would be of great help especially for those who would be tempted to take the 'path'.. I am sure you already planned this, right? Thanks!

errr....the shingaclone is not ready yet.....?????

gabanyayaya,
It's in progress.. we should hear something from ccschua soon.

Went down to pasar road this morning. Bought a 75VA 12-0-12 tranny and some accessories.

** Remember to bypass the power supply and ground to the analog section **

I have hooked up the Peter Daniel 8V DC regulated PS. Next on the list, modding the cap and remove parts on the CD mechanism. More photo to come.

Added on November 16, 2008, 11:50 pmI am surprise at how good the Transport sounds, after I have the mechanism fix to the board and the huge 75VA tranny. What I found is better details especially the instruments. On certain tracks (Vivaldi 4 seasons) I can hear the background violin. Better transparency and coherency. I used mostly Sanyo Oscon, next upgrade is the audio-gd external clock.

beats me why you would want to use a 24V tranny at phreaking 75VA for the whole thing..its just big..big..big..big..heavy n expensive.

Not to mention it would make ur regulator perform worse since more drop-off voltage need to be shed by the regulator=more heat=more noise=less regulation..and not to mention the itsy-bitsy heatsink mount?

Whats the peter daniel regulated PS? macam interesting

From the pictures it seems the tranny has the center tap connected, and has only 2 diodes on the ps board.
The tranny is only outputing 12V in this setup, no?

Refer page 1 for the pdf document. The components recommended are actually all Blackgate Std, but I manage Oscon cause it is available here.

The heatsink is on the way from Farnell, costs me RM 16 (and it is huge). The regulator runs hot actually.

Many trial has been made about the power supply, the best is still blackgate with the MSR 860 and 7808.

Now the shigaclone is rock solid, help by the weight of the tranny.

Can u see how simple it is to be done. Took me some time tough, cause i am noob here.

24V centre-tap, two diode meaning full-wave rectification with no bridge since centre-tapped. Output unreg unload is around 34V, drop out to 8 (26V drop off by reg) and small filter values, shuld haf bad ripple and extremely hot thermal situation.
