Up for sale here is this new Supertech yellow film capacitor. This is a brand new axial non-polar film capacitor, and is rated at 47 uf 250v DC. This cap will work great for you, and will sound wonderful in speaker crossovers, though it has other uses as well. I have various values available, in any quantity you want.
This is a brand new cap, made in August 2022 by Supertech in Taiwan. It is a MPT (metallized polypropylene film) capacitor, which are much higher-quality than the everyday MET yellow film capacitors. These are self-healing capacitors, rated from -40°C to 105°C. They are rated at 10% but generally test within 5-6% accuracy. These are all matching, with the yellow body and dark green ends, so they will look nice and uniform for you. I had these custom-made for me, and they are fabulous! I ordered a huge quantity of capacitors in order to offer them at the lowest prices, and had some special values custom-made as well. Please see my pictures for details and dimensions.
