Hello Fran did you use also the caps before and after the awslr like BMW850?
and also separate transformer for the 5 volt .
I will try the awslr tomorrow.
Can you give me some more info how you do it?

The awslr is fed by a cap-7812 -cap, nothing after the reg. Haven't done a separate 5v yet...... but the pics of how to wire it in is back a page or 2

Fran, I think you should try 5V regulator without any pre-regulation. If AWSLR won't do it, find something else. I'm pretty sure that 12V 3-pin regulator is "masking" purity of a good discreet 5V regulation stage.

As it is right now the awslr is supplying the 8v to the whole player. It's easy to remove the 7812 - I'll try to get to it tomorrow....

Hi Fran,

Peter is right, you should try AWSLR 5V regulator without any pre-regulation.

Rudy

Do you guys mean feed the awslr directly from the diodes? Or do you put a crc just before the awslr?

I would imagine the latter (with crc) - can't see any regulator being very happy having to deal with high AC ripple

I have first a 1000uF FK Black gate then ALWSR then 1000uF STD Black gate.
You also have a Trichord Clock 4 to try, you will be amazed?

Hi Rudy,

Did you experiment with a Blackgate "Afterwards" since ALWSR themselves advices to use no caps at all afterwards...
(ALWSR Manual 3.0 WARNING AND CAUTIONS...THEY TALK ABOUT INSTABILITY)

The 8V and 5V regulators came in 2 days ago....so...

BTW
I see you using a puck...how did the puck-story end ???

Is that not depending on what configuration you use on the ALWSR board.?
Rudy do you use tracking pre regulation on the ALWSR board or not...

I do not think it is wise to use no pre regulation at all (see also their manual) in this case.

hello Fran and you must also bypass the 5 volt regulator on the board
now you use use 3 regulators in a row with the best in the middle .
