“Pucks” & “Cones”.
A one -piece “spun” bare
metal of a TPA-150 main/
bottom chassis.
The new preamp
chassis is basically bored
from solid blocks of pristine
aircraft-quality aluminum
and now features a massive
1" thick top plate!
In addition, the
sides of the chassis are now
a full 1/2" thick. All RCA
jacks in the back are recessed into oversized holes
counterbored from the outside showing the true thic kness of the outside wall.
We will continue to
use the Black Diamond
New Power Amp Chassis !
“Metal Spinning”
is a procedure that dates
back well over 100 years.
Surprisingly, most people in
the metal fabrication business these days have never
even heard of it!
While others may
have heard of it, there are
only a couple of dozen people in the entire US that can
"Pucks and Cones" combination (see picture) for stability and height underneath
all of our power amplifiers.
However, as a result of this re-design, the
preamp chassis is so massive and rigid that it will handle any sound-robbing
(preamp level) vibrations
with ease. Because it no
longer needs as much mechanical clamping/damping
of the bottom, we have removed the "pucks".
Note that we will
continue to use the pyramid
actually do it, and this is be-
cause it was handed down
from father to son!
This procedure
(soon to be seen in it’s entirety on our web site)
makes a one-piece round
chassis (see picture).
If you want a truly
round chassis, AND have it
be only one piece, this is the
cone feet as before.
Another added
benefit is that removal of the
pucks will also lower the
overall height of the preamp
from 5 1/2" to 4 3/4". This
lower height also makes it
useable with many more
audio racks.
Readers Note : Some of the
best news is that while these
chassis are much more expensive to produce, we will
not be increasing our retail
prices until next year!
only way to do it.
The chassis are so
structurally strong and inert
that they handle any soundrobbing vibrations with ease
and gives the best look we
have seen to our amp cha ssis. Even the TPA-30 and
the TPA-60 chassis will be
back-engineered to accommodate this new design!

Electron-Beam Laser -Welded Chassis !
A perfect marriage of “old and new” -
We start with a perfectly
“spun” chassis. (see above
picture)
Then, any welds
that are necessary are done
using the very latest in
“Space-Age” technology—
The Electron-Beam Laser
Welder.
This makes the
chassis itself (and especially
the electrical earth ground)
totally contiguous and gives
an invisible seem to the outside of the chassis.
Additionally, it is
so strong that it becomes
even harder than the metal
itself. This is why it can be
used for spacecrafts and the
like.
