That's similar to mine, but mine has two 1N4148 diodes in series,
back-to-back, total of four diodes.

However, after I did that, I got to thinking that it would be better with
only two. Or that there was no need for four. (Don't ask me to explain,
it's been a long time since I've thought about that.)
