So, I put four new 18,000uf caps in my B&K EX-442 amp the other day. I put some bypass caps across all four on the rectifier when I built my PL 400 as suggested by Lee. I am going to put in two new BR one on each board of the 442 and wanted to know what caps and where you would put them on the 442. I was going to use 8 Panasonic 2.2uF across the rectifiers , wrong ??
