Hi all, to summarize I cant work out what the windings ratio, or rather what the VAC output of the transformer is.
A cliente came in with this GRX7 that is a mixer/power amp, quite old thing. Said it stooped working so he opened it up, saw a loose wire and connected it to where he though it went, but of course that didn't fix.
So i open it up and found the transformer was not connected up.
The transformer has 2 primary windings, and 1 secondary winding I live in Spain and we have 240VCA so naturally the to primary coils where connected together, but there wasn't continuity on the primary, so i separated then to find it was only one of them that was an open circuit.
So to determine the voltage output on the secondary winding i decided to just hook up the mains to only one of the primary windings with the secondary winding disconnected obviously (coz the voltage should be 2x since im using 240 on a single P. Winding), and then mesure the voltage on the secondary, and half of that should be the right voltage, right?? I know that's a bit of an assumption, but any way.
When i did that it would just blow the fuse, I then put a slightly bigger one but still blows it. so im guessing that primary has had it too. It measures 4 oms with the multi meter
Any help is much appreciated.
Thanks in advance.
