Bush TR82C - help request

I think the 500u cap is C33 on the Trader sheet. Definitely replace. In fact all electrolytics should be replaced. The modern value would be 470u. 1000u would be OK. 220u will work but give slightly reduced bass. I can't see the voltage rating but even 10V is enough. The original may be as little as 4V rated.

By "wiper", Crackle means the centre tag of the volume control.
