(1) Someone replaced your original 2/2/1 with a 3/3/2. You can use 3.3, 3.3 and 2.2 to replace it...or 2.2, 2.2 and 1 uF. It will not make a difference. Icon_smile But do use 450V rated caps here.

(2) Yes, the original separate 8 uF and 10 uF caps were replaced with a single 8 uF/10 uF can. You should replace with a 10 uF, 450V cap in place of the original 8 uF.

Now, the original 10 uF cap was in the B- (bias) circuit. Here, you want to use a 10 uF, 50 volt cap. On this one, the positive is connected to ground, and the negative is connected to B-.
