JLM2503 Output transformer. Can be used for API 2503 type DIY projects. The transformer has 4 identical 150ohm windings that are quadfilar wound. So can be used as 1:1:1:1 or 1:2 or 2:1 or 1:3 or 3:1 applications. It is physically identical in size to an AP2503. The top black PCB termination for the 4 windings stops the most common internal shorting failure the original transformers have. The solder pad strip on the top PCB allows for direct soldering or wires or gold socket strip like we use in our our DIY kits.
