Choosing replacement bridge rectifiers
All stock bridges in these games are 35 A, 200 V with lug terminals, marked something like MB3502 or MB352. Any bridge of at least that rating fits; a 35 A 400 V lug-type bridge is a sensible spare. Read the marking on the part itself: some retail "35 A" packs contain 50 V or even 10 A (1001W) parts, which are not suitable.
