A solid state rectifier is also useful for testing to see if a rectifier
tube is bad. The simplest test is to swap in a know good tube, but you
may not have all the varieties on hand. This solid state rectifier can sub
The B+ voltage will be higher with a solid state rectifier than with a
tube, but for quick tests it's simpler to have one SS rectifier than 4
I also keep this in my first aid kit when I'm playing out. If the
rectifier tube fails, I can get through the night.
