[QUOTE="fdlsys, post: 771685, member: 2310"] Fully disconnecting the Centre channel from the PSU will have no ill effects. In case of high amp bias (idle current), channel that is not used (not even a signal cable or speaker connected to it) is still consuming current which adds up to the total heat. If the disconnected amp channel was biased high, you will have a small benefit of slightly more current being available for dynamic peaks and perhaps marginally lower AC ripple. In total - 1/5 less stress on the transformer, caps and heat generated. Rybicons are good caps, used routinely in many of the good quality Jap hifi components. Look for as high temp. rating as you can get. Another good value for money option is Hitano. Doubt you will find any other brand in the same price bracket. Perhaps Cornel-Dubilier if RS might still have some older priced stock. :2thumbs: [/QUOTE]
