If the rectifier circuit does not have a feature to slow the high voltage from coming up to full: The life of your tubes will be severely shortened. A tubed rectifier circuit allows the tubes to slowly warm up to full operating temps. Because there is no warm up of a rectifier tube when using a solid state device, it is critical that a standby switch be used that will allow the power tube filaments to warm up and generate an electron "cloud" around the cathode before high voltage is applied. This will prevent "cathode stripping" in the power tubes. It is a good idea to use a standby switch when using vacuum tube rectification, but it is critical when using solid state rectification. My Cary SLM-100's have SS rectification, and a standby switch. My BAT VK-D5 CD player's tubes always have a small voltage to the heaters, keeping them ready for use, in standby mode.
