I recently got a twin cabinet in pretty bad condition. first and foremost, I checked the owners manual off a pdf I found, and according to it, the machine labelled L has the power supply, but in reality, my one has it on the R machine (and the power cable is also cut off). Is there any explanation for this other than it being modified? also I'm thinking of replacing the PSU since I read that they usually fail anyways. Are there any recommended PSUs that won't break the bank?
