Adding a fan to the chassis next to the transformer makes the unit live
alot longer,
air-flow inside the unit was completely non-existant before this.

A few years ago I made a little fan on a post, attached to a magnet that
I placed inside the R4B. The magnet holds it in place and it comes right
out if you want to take it out. I rectified the filament voltage for the
fan. It points at the transformer and makes it MUCH cooler than before.
I always thought they ran a bit too hot.
