More Information About Pocket Amp 1
Here are some pictures of Pocket Amp 1,
the first model of the Pocket Amp series
which I began building while still a fourth
year Electrical Engineering student at
Ryerson University.

This amplifier was built into a portable
case with a transparent window on top, to
showcase the high quality electronics
components used for its construction.
This amplifier  looks much nicer in person.
I really took my time when building these
amps, and pretended that each one would
be for myself.

The amplifier was built in the classic and
time tested Non Inverting Feedback
configuration. I must admit that after
mailing away the first amplifier, it was sad
to see it go. Each one was special a few
hours to build.
One of the reasons why this amplifier
sounded so nice was due to the large, 1000
microfarad capacitors (the five circular
objects located on the left side of the  
picture, below the blue LED). I actually
built a test amplifier circuit and brought it
in with me to many  electronics stores.
With this test circuit, I tried every single
make and model of capacitor the store sold
until I found the type that sounded the best.
The capacitors used in this amplifier help
to provide a low frequency 3-dB rolloff
point at 5 Hz! The upper cutoff point is
located at 40 KHz, well above the range of
human hearing.
Here is a top view of the amp,
showing the chrome tip volume
knob.
Three amplifiers. :)
Next is a picture of an amplifier still being
built. Rule number one of soldering:
"Always apply heat first, then the solder".
Thanks to my old boss Mr. Nick at
Samsung, who would always stand behind
me and say that.
A few Pocket Amp 1 amplifiers have
come back for repair, and I have always
been happy to repair them at no cost, just
as I originally promised. It is my pleasure
to fix them actually.
