Default Hacker Democrat capacitor substitution

Hi Folks.

I am changing some dodgy looking capacitors in the amplifier of a fairly battered Democrat I know valve sets can be fairly forgiving due to wide electrolytic tolerances but not sure about transistor sets? Do you think I would be OK with the following substitutions?

C4 and C8 400uF 10V change to 470uF 10V and C21 40uF 16V to 47uF 16V? I will fit some if they are OK, the old values seem as rare as hen's teeth or very expensive!

Regards, Kev.

They will do nicely, when it comes to electrolytics anything a bit bigger in both capacity and voltage is OK.

Thank you for that Merlinmaxwell much appreciated And for the general rule about a bit bigger I forgot to mention C2 at 80uf 25v so I assume 100uf 25v which are easy to get hold of would be fine as they seem to be the next easily obtainable new component. 80uf are more difficult and I dont want to use NOS ones.
Thanks once more
Kev
