Today I realized why my CD`s are always sliding when Shiga starts reading or change speed, the Puck is not straight,it is touching the CD only on the inner Side.It`s a bit more than 0,1mm I think,what fits under it.Any Idea?
Regards DT

Adjust inner puck with a fine sandpaper and will fit perfectly.

Where do you want to solder LT1086 ?
If is LT1086-adj than you have separate pads on power supply.
If is LT1086-5 than you can solder on V1 and V2.

It is 1086-adj and some Contact Pads are gone from desoldering LM317 -adj.

Post pictures to see what you did, of follow traces with a multimeter and solder to nearest points.

Wanted to follow Traces, but when the Pads are gone there is no Contact.Today i got some 3 Dioptrin Glasses,now I can see where the Traces go from Middle and left,not shure where the right one goes:.(looking at the Print).

Thank You ,now I got it. Today the Mini-Regs arrived.Leds are missing,is it just as Power Indicator?

Yes, just a power indicator and is performing better without.

Hi all,
Is there any consensus about what to do regarding the trimmer on the laser head? By-pass cap, fixed resistor?
Tibi, Dimitri?

 

[spartan]

has anybody tried the silver mica caps being sold here: capacitor_film_smica.html

They're much cheaper than the dubilier.

Use only a 100pF silver mica.

Because there is a difference between Suntan and Cornell Dubilier.

So get rid of the trimmer?

 

[iTiberius]

So get rid of the trimmer?

No, jut add 100pF across.
This was discussed in this very thread which worth a full read.

Tibi

 

[spartan]

Oh, I'm sorry, but the value mentioned before was 1000pF and it wasn't clear if there is consensus about leaving or dropping the trimmer.

In case XO tentlab is on board:

on the schematics, for C59 it is indicated 10nF NPO (1nF Silver Mica). Would a 1nF silver mica be better than 10nF silver mica here? Or was it a print mistake?

If you are going to use a MLCC, use 10nF NPO.
If you are going to use silver mica, use 1nF.
