We are now selling best price from Japan on this Oyaide MTB-4 Power Strip that employed 2.0mm 4N silver wire for its internal wiring connection. Usually, an annealing process is applied for un-stiffening the metals. However, Skin-Pass process is applied for 4N silver wire of MTB-4. Skin-Pass process is the rolling process operated to improve the quality of surface treatment.

The chassis of MTB-4 is made of 2.0mm thick brass board which is highly rigid and has excellent vibration damping property. For Its surface treatment, a combination of nickel and chrome plating is applied to control the hardness of the body. Coupled with the shielding effect of brass, nickel plating reduces exogenous noise in wide frequency range.
Audio grade solder
For the soldering connection of MTB-4, we employed SS-47 audio grade solder.
Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.
Electromagnetic wave absorber
We installed an electromagnetic wave absorber at IEC inlet part. It reduces magnetic noise and distortion generated around the contact.
