What did World War II have to do with the Rock & Roll Revolution? And who really invented the overdriven guitar amplifier? Hartley Peavey takes us all to school on the colorful history of modern music in his first white paper, "How This All Came About."
Chapter 1 - How This All Came About
http://peavey.com/monitor/pvpapers/Chapter1.pdf
QuoteIn the late '60s, I attended a NAMM show at the Chicago
Conrad Hilton Hotel. In those days, the various
companies rented a room (or a suite) to display
their goods. While I was walking the halls of the hotel,
I came into a room where a guy was playing
one of those cheap Japanese guitars of that time
that had a Formica top and four pickups. This was
plugged into some cheesy no-name amplifier and I
remember being shocked that this lousy guitar and
that cheesy amp sounded so good. I stood and listened
for awhile and I noticed that there was this
guy standing there with long hair and coveralls. He
might not have looked too out-of-place in Mississippi,
but at the Conrad Hilton, he stood out. He was
explaining to the executives of the company how his
little box gave the amp more power. He was selling
these boxes out of a bag he had strapped around
his neck. It was the first time I'd seen Mike Matthews
and encountered his little effects box that he called
the "LPB-1 Power Booster"... Mike indicated that
he was selling these power boosters, and after he
stopped talking with the people in the room, I asked
him how much he wanted for one of his boxes. He
replied "$8.00," and I bought one on the spot.



The decade was the '70s, and we had a problem. Our new CS power amplifiers were producing unprecedented volume levels, but we couldn't find loudspeakers that could handle this newfound power. Read on to find out what we did, and learn how you can save your own sound system by protecting "The Weakest Link in the Audio Chain."

Tube amplifier tone comes from a complicated series of events. Hartley Peavey isolated the five main ingredients needed to recreate realistic tube tone and devised TransTube®, an analog technology so exclusive that it's covered by three U.S. patents and guarded like Fort Knox. But just how good does it sound? Good enough to fool most music biz "golden ears," for starters. Read this Hartley Peavey white paper, and then plug into a Peavey TransTube or Vypyr® series guitar amp and hear the sound of innovation.

Can an amp put out more power than a "wall socket" can deliver? Hartley Peavey does the math and discusses the difference between peak power and continuous power in this installment of "The Peavey Papers."

Although magnetic pickups seem to be shrouded in mystery, understanding how they work is simply a matter of examining the science behind them. In the fifth installment of the Peavey Papers, Hartley Peavey pulls back the curtain to reveal the secrets of "The Ancient Order of the Mystic Magnetic Pickup."

Standby... For The Truth! In the sixth installment of "The Peavey Papers," Hartley Peavey takes an in-depth look at the guitar amplifier "standby" switch and reveals its surprising true purpose.
Chapter 6 - Standby...For The Truth

Most guitar players have heard that operating a tube type guitar amp without a speaker plugged in can cause problems, but few understand WHY. Hartley Peavey explains why speakers are important in or out of the circuit.

I particularly enjoyed his comparison of PSU capacitors to a flushing toilet (chapter 4).

.. and net profits are also compared to a flushing toilet (chapter 11).

Interesting to see he believes in the fabled "cathode stripping" of indirectly heated tubes though. There's no direct evidence for it and some very good reasons to NOT use standby switches at all on tube amps.

It's always a hot (no pun intended) topic on diyaudio. What those guys don't know about tubes isn't worth knowing.

Especially George from tubelab ...
