As promised I started to build PiTbull-Scaled-Down version for a good audiofriend.
This afternoon I will take the contraption to 2 other audiofriends...ohhhh...I am looking forward to the look on their faces when I start the Skeleton up.
at the moment I am listening to it without the 8V ...or is it V8
power supply.

Hi Fran,
You will not believe this but just a second ago while browsing thru my incredible amount of spares (looking for my friend)........I found your puck !!!!!!
I do not know how it got there but I must have ruined your first one and by throwing that away I mixed things up and forgot all about your second one.......
HAPPY CAMPER
Ok....
it's sitting on granite which in turn sits on damped springs,
reclocked,
using rf attenuators to knock the ttl signal down,
ero 1837 cap for c906,
ebony screw puck,
that's all I can think of right now! But I did many of the mods through the thread as it progressed.
I have the new one playing now just through headphones and I have one problem. The dac seems to slightly lose lock between tracks, I get a little blip at the start of each new track. I don't remember sseeing this before in previous builds, anyone get this and solve it? The other odd thing is that if you press the toc switch with no cd it searches and instead of the customary 00,this one displays "70". Haven't seen that before either.

Hello all,
Yesterday I taken apart a new Boombox and is now playing, and this one is not better than my full modification Shigaclone at the moment.
This I have changed look at this PDF file so you know what I talking about: http://tim.cheapo.cc/images/CD%20player%20mods.pdf
R4 and R5 I removed and 2 smd caps 3 and 4
E5 removed and a 2 x 33uF Blackgate N super E-cap there for in place.
No jumper from 5A to 5B the print was intact.
Power supply:
1000uF FK Blackgate LM7808 1000uF FK Blackgate, about the last one I have no more Blackgate STD so I used the BG FK.

Guys - if I click on Peter's original link back to this Bobken reg. circuit it takes me to this page!!
EDIT - sorry guys - just tried it in IE6 rather than my usual Google Chrome and it works fine ........................ bloody Google chrome!!!

Hi Peter,
The 1uF/500 Vcap how did that perform against the standard cap that comes with the boombox.
Where you in a situation to evaluate it in a direct comparison
(without other tweaks in one go I mean)
My experiences with Vcaps are great...but obviuosly I wonder what it does in this particular place.
I will buy the Vcap for my friend to try it out....unless ofcourse...etc etc

I got this problem when changed to mundorf sio 0.01uf
Solder back the original caps then bypass the mundorf
Now the shiga read all the cd, hope you success .......

Hi guys, a few questions (again)
1. Has anyone determined if there is benefit in separating the mechanism from the PCB?
2. I've unscrewed the two screws that appear to hold them together, but they're still attached to each other, so any ideas?
3. there are lots of wire links on the PCB. Has anyone tried to replace these with low R inductors threaded with ferrite beads? I tried this ages ago on a Rotel 855 cd player and was pleasantly surprised by the drop in noise floor and increase in resolution.
As always, thanks.
Ryan
PS, will be posting results of a Theta data III transport vs Shigaclone shootout shortly.

from memory I think the mechanism is held to the pcb by some motor connections too - it's soldered down so these need extending with wires.
this is from memory so i could be wrong ...................
I did separate mine but just to give me more room for component replacement - in theory there should be some benefits but it's likely to be subtle.

Yes, you need to desolder the motor connections from the bottom PCB. You will then need to wire back in extension wires or whatever if you are mounting the motors separately. Don't forget that you will also need to extend the lever on the travel switch.
The benefits are very small - although it does give you good access to swap components etc. FWIW, its much more important to mount the whole mech on something really solid on 2 standoffs.
Don't ever remember anyone changing the wire links......

This one is for Fran...the last puck standing (soundwise) 
You only have to listen to track 2 of Dire Straits Water Of Love to fell in love again with your puck....
How all this is possible I do not know and actually I do not care.....wood versus acryl used in a digital surrounding ....beats me..

I didn't complete the new transport yet, had some problems with its functioning. Last time I checked V-Cap vs original cap I wasn't sure if V-Cap was better, but this time I installed it directly on a bard, which should be better. Also, my previous setup wasn't optimal, so any findings could be less than accurate.
There is new grade of Teflon V-Caps: CuTF which are clearly better than previous TFTF type.
