pass 20 watt class a
has anyone built the 20 watt singe ended amp Nelson Pass designed abot 1977.
I wondering if c1 the input coupling cap is really supposed to be
1000uf. After a look thru my parts collection I find that I have
nearly every thing to build one
I have, and yes, according to the original article it is 1000uF.
I did enjoyed my 20W ClassA right until my voltageregulator fried not only itself, but the ampboards as well :bawling:
My ClassA amp
Good luck building it, but don't take lightly on the Pass' warning: "For this amplifier, there is no such thing as too much heat sinking for the output stage. Extravagance in this area is no vice, and good ventilation is similarly very important."
