Point To Point Wiring
I’m a supporter of point to point wiring, especially for
simple tube amplifiers. I’m not against PCB but point to point wiring gives me
the freedom for design change anytime, not to mention the freestyle wiring for
shortest path connection.
With proper planning, I can design the amplifier such that I
do not need a lot of wires to connect the components together. The pins or legs
of the components will be sufficient for the job. It may not look good but it
is one of the best ways on getting the job done – fast, accurate, short and
direct! It may look messy but the logic is there, not to mention the
improvement such methods bring. Also, sometimes I would like to keep the
reusability or upgradability of the components for future use and therefore
some connections might look a bit odd. Everything is done for a reason.
别人笑我太疯癫，我笑他人看不穿！
Since I started DIY, I love to look at the internal design
of the amplifier to see how creative the designers are in wiring up the
components, especially for point to point wiring designs in tube amplifiers.
Some are really well executed that they really look like a piece of art.
There are some that I do not like too where they’ve taken
the “look” too seriously that they compromise on the most important thing of
all – simplicity and shortest signal path. They make the connection look so
properly arranged that they’ve to resort to all sorts of additional wires,
turret boards, binding posts to get the job done. Also, those neat 90 degrees
bents or tight bends on the components are just annoying. Yes, it looks nice,
but the electrical properties of such bends are not preferred – they act as
antennas and they either transmit or receive noises. Will it sound good? I bet
those natural curves with shortest path will be many times better!
So, don’t be too happy if the internal look too nice.
Analyze how the things are being done before deciding to splash your hard
earned cash on them.
