ntAs promised, we cracked open the Ion iTTUSB Turntable to see what makes this gadget work. The review we published in the TechRepublic Practical Gadgetry blog and the original First Look Gallery are still going strong. Apparently, music and music recording inspire passion in much of our membership.
Here is the iTTUSB in all its glory before I start the cracking open process.
If you look back at the First Look Gallery you’ll see that this is what the turntable looks like when you take it out of the box.
This is the flip side of the platter where the vinyl records sit. The drive belt has been removed from the center spindle.
The three small, but very important parts of the iTTUSB Turntable include the belt, the weight for the arm, and the stylus where the sound originates.
Input / Output
Power goes in and sound comes out.
Off with the feet
The big rubber feet on the bottom of the iTTUSB turntable keep it steady during playback.
Next the screws
Once the feet are off, the screws are the only thing left between us and the insides.
Circuit boards and wires
Here is the inside of the Ion iTTUSB Turntable. When you think about it — there is really not much to it.
The big green circuit boards in the bottom corners are the start / stop switches that control the spinning of the turntable.
As with any sensitive electronic equipment, power regulation and control is paramount.
This board sits right in the center of everything. It is passing power wires to the speed controlling board in the corner.
This board controls the turntable RPMs — 33 or 45.
Here is a look at the serial number. Manufactured in April 2007, no too bad considering it came to the U.S. on a boat from Asia.
This the stylus arm housing.
Arm base lit up
This image shows the stylus arm housing with a flash. Note the thin wires — I wasn’t willing to risk Breaking something in there.
On / off
Your basic on / off switch. Notice that it is held together with glue and not solder.
A little closer
This is a little closer look at those chips.
