Ge Transistors for old times sake and Fuzz Face origin (maybe)

I found this little historical dump of germanium transistor info from the olden days:

In there I noticed a reference to the "Ge Transistor manual".   For those who don't know this book was probably *the* most popular reference book for transistors from the time transistors started to at least the mid 80's.   It contained a large number of standard circuits using transistors.  It was pretty much the recipe book for transistor circuits.  It rapidly grew in size each year from Edition 1 (1957) at around 100 pages, to Edition 7 (1964) to around 330 pages.

... yada, yada, yada ...

The most popular edition was perhaps edition 7 (1964).  In there it shows the basic template for the fuzz-face as "Direct Coupled Amplifier" (p102).   Perhaps this was the inspiration for the fuzz-face.   (The basic idea actually appears in earlier versions of the Ge Transistor manual, and probably goes back further to tube amplifier designs.)

According to the water analogy of electricity, transistor leakage is caused by holes.
