Up for sale here is this set of two (2) Supertech yellow film capacitors. These are brand new axial non-polar film capacitors, and are rated at 4.7 uf 250v DC. These caps will work great for you, and will sound wonderful in speaker crossovers, though they have other uses as well. I have various values available, in any quantity you want.
These are brand new caps, made in 2023 by Supertech in Taiwan. They are MPT (metallized polypropylene film) capacitors, 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.
