Among other palces you should be able to get a free copy of the circuit diagram here: https://www.radiomuseum.org/r/bush_tr82ctr_82_2.html
The electrolytics with red and black ends should be replaced on sight. The other electrolytics will be dubious too. Even if they reform after a while, they are unlikely to stay good for long.
Electrolytics have very wide tolerances, often -20% to +50% so the replacement values are not at all critical. The voltage rating of the replacement is likewise uncritical provided it's at least equal to the original. So a 63V rated part will be just as good as a 10V part in this radio. Don't overdo this by using a 250V rated part though it will be OK in practice.
If replace non-electrolytic capacitors the voltage rating in a transistor set like this is completely non-critical.
