Fender champ 110 transformer

[Screamingdeal]

Just looking for some info on this transformer. Can't seem to find anything online. Stamped number says c033613

Black to black reads 9.8 ohms
Red to red 1.5 ohms
Red to red/yellow 1.1 ohms
Red to red/yellow 1.1 ohms

Keeps blowing fuses, trying to eliminate components.  Any help is appreciated

Disconnect secondary (red wires), if still blowing fuses you have a shorted power transformer.  If not, it's something downstream, likely power transistor or filter cap.
