What are some of the differences? Input and outpu capacitance ?

I just found out on another forum that what I am looking for is PFS Technology Power Plate Amplifiers by Rick Wilson Does anyone know where I can get this? Thanks Big Mike

There used to be a cd on how to build these transistor amps that had all the info not part of it. Where can I get a copy I would love to build a 2 transistor amp. Later on maybe a bigger one. Thanks Big Mike

I was curious if the Predator 10k is still being made? I notice some places have been out for a long time. I would like to try the 27" out, but i do not want one that is not being made anymore. Thanks Big Mike
