Hi-Fi Preamplifier
By Graham Maynard from Newtownabbey,
N.Ireland
Notes:
This circuit was submitted by Graham Maynard from
Newtownabbey, Northern Ireland. It has an exceptionally
good high frequency response, as demonstrated by applying
an 100kHz squarewave to the input. I have
produced some response graphs using Tina Pro to highlight
these characteristics.
