Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads. Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function.

Diodes, silicon that is....
I've got a bunch of different kinds, and I really don't grasp their practical application as much as I'd like. Here's a few I'm considering using in the power supply of my next tube amp; a PP 1625 amp.
BY228 damper diode - 1500V/5A (axial, Phillips)
BYW95 fast soft-recovery controlled avalanche - 600V/3A (axial, Phillips)
RU3A fast recovery - 600V/1.5A (axial)
FMU16S fast recovery - 600V/5A (TO-220)
FR805 600V/8A (TO-220)
In past builds I've always been overly cautious and have never used diodes under 1000V rating. However, the PT I'll be using has a B+ of 300V using a FWB. So a 600V diode would be fine for this circuit; right?
What about these damper diodes, controlled avalanche, or fast recovery?
I've never seen these types used in tube amps. It would be great to hear from some of you in the know about the practical application of such devices.
