Hi Matthieu,

I'm no engineer but I feel that isn't likely what's happening. I don't know what is causing this behaviour.

Bear in mind Steve's was unhappy with a regulated/lower voltage on the MINUS rail, not the one with the big cap. The -10V rail on Steve's just has the standard 1000uF poo cap.

Simon

Oh, congratulations Ray, she's very cute!

Any mods planned or will you keep her standard for the next 15-20 years?

Congratulations Ray!

LOL @ Simon

Servo amps - I used LM317/337 at 7.5V and never had my player skip a beat, infact it tracked better after (quicker to lock onto track) but I may have imagined it. Bear in mind you have to do a bit of re-routing of the power lines for one of them. You have to isolate a track from one of the big caps to one of the amps and connect it the other side, then you can remove a jumper for your new reg input/output. It should be clear looking at the service manual layout.

The amps only output 5V signals and if you use 7-7.5V regs that's enough overhead for amp and regulator, i.e., 10V-->7V-->5V.

Thanks guys. I think i'll keep her standard first, see how she sounds first, and maybe, if I don't like her tone after a few years...
May have to go shopping for a pink soldering iron, who knows...

Ray

We are at least 2 to have noticed a faster reading
And I did re-routed one of the PS, one jumper removed (positive one) and a wire after reg to after jumper pin.

Bottle-fed I hope? (as a valve/tube man...)

Regards to the track re-routing;

1) Remove U234, U161 and U237 shown in red to isolate the drivers from the raw supplies.
2) Insert -ve reg at U234 (use holes as input and output)
3) Insert +ve reg at either U161 or U237 (use holes as input and output
4) Connect blue wire as shown (you can use any colour )

Simples.
