Apologies if this is in the wrong section for this posting this but I was not sure which category it should be under.
I have a minor issue with the circuit board in my recently purchased Dapol Class 22. As hopefully can be seen in the photos there are two SMD resistors (R2 & R3) that appear to have either suffered heat damage or have been manually replaced with another variety as they do not match the other resistors. (in fact they look more like the capacitors on the PCB rather than a resistor!) There's also a suspiciously dry solder on the white wire which will also need attention... All functions appear to work well under DCC with the exception of one of the cab lights so it only a minor problem. Having purchased this second hand I have no idea if this has suffered any sort of mistreatment to cause this damage – or warrant repair if that is what has happened. Would anyone be able to assist me in identifying the values of these resistors so I can attempt to replace them - and hopefully make a neater job of it if I can? I'd rather not have to spend £30 on a new PCB for the want of a few pence for resistors and some careful soldering! Thank you.
