Electrolytics vs polyester films.

I was peering around in a small stereo reciever I've been wanting to recap, taking notes of the values. I bagn to look around on Mouser, and I've noticed I could spend a little extra money and replace all the 1uf - 4.7uf caps electrolytic caps with polyesters of the same values.

Does anyone have a reason as to why I would not want to do this?​

Well... with the greatest respect... is it worth it ?

Also will the film caps physically fit, and if they don't then the end result will look a mess :) Not only that but any extra wires/lead length is an open invitation to pick up noise degrading the performance.

By all means have a go, but I would definitely get parts that fit the PCB.

If they fit OK and you feel the receiver is worth it then give it a go. Good electros last a long long time in normal use... 10, 15 even 20 years as long as they are not cooked. Film types won't deteriorate... up to you :)
