Hi all, Tibi,
I have printed out the clone circuit as big as possible (A0) for study purpose. I see that Q2 feed pin 18 of connector J4 and pin 3 of connector J3.
I will give that pins a separete 78lo5 reg, this means Q2 is unnecessary
and can be omit.
Mine questions, is this worth full, if yes, what to do whit the pins 11 and 12 of LA6541, they too become unnecessary.
This to separete the power supply as much as possible.
Regards

Hi zjaakco,

Q2 also power entire Shiga trough L4 bead.
Q2 is part of internal LA6541 regulator which is quite good.
J4 pin 18 is for infrared receiver and J3 is for CD switch door. Changing this to a separate power supply bring no sound improvement.
Trough Q2 a system reset is made by LA6541 at very power on. This is the main reason why this regulator is included in this driver.

Tibi

CD Puck and trafo not included - what about the remote?

Just so I'm not missing anything... I wan't a really full kit :-)

Is this with the rev-2 board?

Can't wait to comparish it against my original shigaclone!

Hi Turbon,

CD Puck, trafo and remote are listed separately and you can order them as well.
This is MKII version, board will be rev-4 or rev-5 depending on how beta testing will go.

Tibi
