I have just assembled new Legato and I am using an LCBPS that I used before with IVY I without any issues. Without load PSU rails are +/-15 spot on. After I hook the Legato the rails drop to +13.7 and -13.4V. Is this normal? The max current supply is ~1.5A - it is impossible that Legato is even close to that. The stated 0.35A should not cause that voltage drop.

Thanks

It looks I am not giving it enough juice - 20VA trafo with 2x15V secs. Bugger!

Is the Legato performance OK on 13.5V supply rails? I do not have room for a bigger transformer.

You don't have much of a choice, do you ?

Go for it, it will be just fine.

Thanks - I will try with TP 30VA trafo - it looks it might fit - I hope it will be better.
