38-7 Chairside - What Is This?
#9

So it was your post on FB yesterday? See? Here it is that much better.

Someone even suggested a bias battery.
Transformer radios do not need them - they can generate their own negative bias. It is mostly used in AC/DC sets.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
