[QUOTE="Timo Ulkuniemi, post: 99962, member: 1978"] Re: Failure rate Hello One solution to take off some load of the regulators is to connect power resistors across input-output. The size has to be calculated so, that alone it would deliver about 0,5V less than required, thus allowing the regulator do the rest. The resistors can be wired to free places in sides of enclosure in order to get cooled there. This takes thermal load away from regulator. I did this to an Allen Heath GL2000 32 ch desk, where PSU was running really hot. After this low-cost modification it started running cool and is still in service after many years. [/QUOTE]
