I have been enjoying the 5V Wow for several months now and it has performed flawlessly. The black finish on the tube proved to be a little less durable, however and was chipping after a few weeks. I was surprised to see brass underneath the paint and decided to sand it all off. I think it looks pretty good with the finish removed and thought I’d share a photo. The only downside is that the bare metal gets tarnished after awhile; the photo at left shows it before and after a quick polish with Brasso.
