My order of caps has arrived. I tried to get the highest grade caps at a reasonable cost.
All the electrolytics are rated for 105C or 125C and 8,000-10,000 hours life. Generic caps are typically 85C and 2,000 hours.
The white caps are metallized polyester Mallory 150 series. The box caps are Y2 rated AC line filter caps.
I'll hold off on ordering any resistors until I test them.
