100 valve amplifiers: A history
« on: June 27, 2015, 10:19:37 PM »
A must-read for valve afficionados.

I have just received the following most valuable reference from Skollie. A unique history of valve amplifiers since the beginning in two parts. I am indebted to him (he has also contributed!).

100 power amplifiers to lift your hat preface.

F_D may consider to make this a sticky. I will not comment now, except to say that it is a remarkable history for everybody interested in the development of valve amplifiers since the beginning of electronics (before even my time!). Many matters are put in perspective.

I distinctly appreciate correctly explaining the innovation of ultra-linear topology, which at the time was with respect, a sad opportunistic piece of deceit without giving credit where it was due.

I personally, who was part of this history for six decades, take my hat off to those who pioneered.

Great resource - thanks Ampdog!

The website has been slightly rearranged and the link is now outdated. Here is the link to the preface of the now four-part history:

I have been doing a lot of reading up on valve amps, and i understand the basic concepts (or at least I think I do  ;D). IMHO this history shows how valve amps have evolved and converged on a couple of quite easily recognisable topologies. I certainly find them a lot easier to look at/understand than transistor amps, which are a lot more complex and varied from one to the next. I can't wait for my Mars kit to arrive and start playing!
