Power Supply Elliott Sound Project 05 revD

[Maximilien]

reHello,

I builded the Elliott Sound Project 05 rev D power supply (http://sound-au.com/project05b.htm) with my own PCB
But once I power it up, I got +15V and -21V.
Before the LM317 regulator I got +/-23V.

And I don't find from where the issue is coming. I doubled check the diode and all are OK.

Could some one help to fond out the issue?

Regards

Because I guess you have them both ... LM317 LM337

I guess it is something with the LM337 circuit.

Have you attached D6 correctly? It may be in wrong direction.

Oh right!!! My mistake, I took a LM317 instead of the LM337... Need to learn reading.

Problem solved.
