Replacing low value electrolytics with film caps
The smallest film caps are metallized polyester in MKT or Greencap form. These are OK and better than generic electros but the best common types are based on polypropylene film/foil type MKF (huge), or metallized film MKP type (v.large). As a general rule, anything over 1uF in MKF is too big as is anything over 3.3uF in MKP and maybe 10uF MKT.
