RE: Selenium Rectifier Lowdown

Hi Phil,
We are still around, having been affected by some nasty seleniums' farting. While their smell may be toxic, so would a blown power supply cap, or oil cap, or solder fumes !

If the voltages are fine, stable, plus if the current draw is minimal, why replace the selenium ? There are some very fine vintage preamps, some still considered world reference, which came with seleniums for their High Voltage Rectifier. Moreover, they were often 1/2 wave rectified ! I agree they may be old and tired, and could smell bad soon, but, they do sound "warmer" than a silicon rectifier adjusted for the same voltages...
