Components for AC-DC rectifier

Hello. I am looking for some advice on components for a voltage rectifier circuit which controls a solenoid. Moisture caused tracking across the circuit board and blew some or all of the components. The part is obsolete but I'm sure the individual components can be replaced as the PCB is in good condition. I am trying to identify the type of bridge rectifier and the orange and blue components as shown in the picture. Any advice would be much appreciated.

The bridge rectifier can be tested with a multimeter. If you find something the right size, voltage and current rating, it will be fine. You are likely to find a wide choice of devices. It is also quite likely that the bridge rectifier is massively over-rated, so it could well be rated at many times the voltage and current that it is used at.

The orange device is a 33 nF, 400 V capacitor. You may find that a replacement will be marked 333 instead of 33K.

The blue device is likely to be a capacitor to reduce noise. The circuit will most likely work without it.

Can you photograph more of the board to give some context?

Sure. This is the original board. There are two identical circuits on there one for the pilot and one for main solenoid, which are both rated at 220-240v

Two bridges on one board is a bit strange.

My guess is that the blue part is an MOV - Metal Oxide Varistor, a transient suppressor. The 250 V marking is common. Anything the same size (and rated for 250 Vac) will work.

Does this board run directly off the mains, or is it downstream or a power transformer?

Yes the control unit puts 240v ac into the board
