[TR] Voltage Stabilizers

[Anthony Rhodes]

Probably it is broken

Time for a new one.   We discussed this recently and devised a decent improved design.  Perhaps someone made one and made an extra one too.  (The added cost is low)

These commercial units are insufficiently protected and don’t even have the specifically recommended filtering.  

I made one many years ago and used the device specifications re: filter capacitors.  And I avoided aluminum electrolytics because these have a limited lifetime especially around heat.  But I don’t have any spares any more.
