As for reliability, MTBF etc, it depends on the choice of components, layout and *cooling*. Low quality, standard temperature (85'C) electrolytics placed near to the transformer or heatsinks in a sealed enclosure with no forced-air cooling are not going to last very long at all in a SMPSU. Conversely spreading the load current between a bunch of paralleled 105'C low-EST electrolytics from a reputable source like Rubicon placed away from other heat sources with forced-air cooling can surely last 40+ years. Lifetime comes down to picking decent components and thermal management.</span></div></blockquote></div><br class=""></div><div class="">Over the years, I’ve had to replace SMPSs in a Korg M1 (twice) EMU Proteus (twice) and UltraProteus (thrice). Not knowing any better, I was probably purchasing the cheap and cheerful ones. I suppose it’s a case of you get what you pay for.
