Very High Frequency Techniques

[Philip Miller Tate]

It is a sad side-effect of the burgeoning knowledge base that such  
elegant design techniques have often become almost lost, replaced  
(but not necessarily superseded) by "modern equivalent" technology  
that may be easier to mass-produce, but necessarily do such a good  
job - a similar situation is where (passive) high Q tuned circuits  
have been commonly replaced by (active) filters and amplifiers to  
reproduce the same performance.

Thank goodness for the combination of open-minded enthusiasts who  
keep an eye on the past, plus that brilliant 14th-century passive  
information storage-and-retrieval technology that is compatible with  
the world's top operating system, the brain. It's called "the book".  
Brilliant. I'm not ashamed to be an enthusiastic collector of these  
historic IT devices myself.

Whenever I go to Hamvention (as Frank will attest), I hunt for old  
transistor circuit books. Not old IC circuit books, note - unless  
they're all 741 and 555 circuits, I can't build them. Older  
transistor books are still useful, though - and neon bulb oscillators  
have dozens of applications.

My tuppence worth.
