Thank you Mihaylov, Gstew and Theob for the encouragement. SQ made an quantum leap. :-)

Hi Mihaylov, Gstew and Theob.

Thank you guys for encouraging me and giving information and feedback on how too power the Juli@ digital part externaly with 5 Volt and 3,3 volt.

Realy very, very worth doing.
Just as reported by other inmates: SQ made a quantum leap.
Thank you guys fore the encouragment.

I’m planning too also feed the 3,3 V intoo the J1 connector.
And both wire pairs too the J1 connector will have P4 sockets.
This will allow me too easily swap in and out filters, post-regulators, etc.
Van on filtering, de-coupling, demping, ect

Constructing the LT 1086 DIY post voltage regulator for the 3,3 volt turmed out too be surprisingly easy. I’m now thinkig of how too build an all linear PSU ‘the easy way’ through building 3 post-regulators.
IMHO biggest chalance for an all linear PSU for most tweakers is the 230 AC -> 15 Volt DC stage. Constructing this stage involves working with letal 230 AC voltage, ect ect.
So starting with an off the shelf linear PSU and than using post-regulation too create an all linear PSU, might be better doable for tweakers with lesser electrical skills DIY. Playing arround with low voltage needs no special safety measures related too personal safety.

So coming months I will be busy trying too go all linear through this route.
