Hey there,

I have bought SYMMETRIC 1A POWER SUPPLY kit - K8042.
I need exactly 15V power supply for my Hi-Fi amplifier.

According to your manual (http://www.velleman.eu/downloads/0/illu ... _k8042.pdf), I should buy 2x18V transformer. However value is on the edge of <12V, 15V> interval (manual: +/- 12 ... 15V 2 x 18VAC). I need exactly 15V power supply for my Hi-Fi amplifier (14.9V or less is NOT suitable!)

There are two transformers which I can buy:

I.
2x18V, Power: 40VA => Secondary winding current 1 and 2 is: 1.1A

II.
2x24V, Power: 40VA => Secondary winding current 1 and 2 is: 0.85A
http://www.tme.eu/gb/details/ts40_047/t ... ing/indel/

I would like to ask you for advice: which transformer is more suitable for my purpose?

Thanks for your help
