I am reposting this from another thread because its important I get this question answered before I carry on with my project.
I had mistakenly been using an over powered transformer in my last project and I'm now building an lm3876 Amp that I need a new power supply for.
I went to the surplus store and spotted a couple of 24V 75VA transformers and figured they'd do the trick.
I've just unpacked them and now I see there are three primary wires
. They are labelled:
120 V 1-------------)
95 V 2-------------)
0 V 3-------------)
the label says
PRI 95/120, 60Hz
SEC 24V, 75VA
So why are there three primaries. Im hoping that this is a supply for EITHER 95V or 120V and that I can just connect the appropriate wire, but I'm not going to assume that.
Can I use this thing or do I have to go buy yet another pair or transformers.
