Radio self-made
5
From Japan
On 2018-09-18 04:21:05
Although it is the only pleasure to make a radio by referring to the old article, the most difficult task is to have parts difficult to obtain. Sansui transformer also became difficult to obtain for a while, but it was sold in a monotaro · · · bought immediately. Moreover, it is cheaper than a special parts shop!

The inventory of manufacturers and dealers has been lost for a while in early 2018. Although it was serious at the end of the fiscal year, it was saved by the long-term inventory of the long-established store in Akihabara. .

Sankyo's transformer has been keeping a relationship since primary school age for more than half a century. Monotaro san, you can purchase as well as other materials We are very sorry. I am satisfied with the quick response. Thank you.

It was smaller than expected and easy to implement. It is easier to use lead wires a little longer.

Production of small output semiconductor amplifier for audio

From Japan

I am glad that it is still available as an existing product. Permaloy core in this size but reasonable price is also good. We adopted it to correspond to the low impedance speaker which becomes a heavy load on the design of the amplifier. There is no complaint in quality.

ST - 17A is a radio transformer, but I used it as a line transformer to put it between the CD player and the pli main amplifier. To listen to the Showa's popular songs, the range feeling is moderate, it gathers in a sweet tone of candy, and I am deeply moved. Since it is said that such inscription has been keeping silent since 1965, there is nothing surprising.

Boost pressure to piezo speaker

From Japan
On 2017-05-18 19:10:24
I tried ST-12 first, but I tried ST-10 this time with slightly over spec. It seems that it can be used as a well-balanced step-up transformer that suppresses the output of the bass part.

As a step-up transformer of a piezoelectric ceramics resonator
5
From Japan
On 2017-05-10 10:19:11
Piezoelectric ceramics oscillators seek voltage but do not ask for current. The step-up transformer achieves the purpose without requiring a power supply like an amplifier. By using ST - 12, necessary sound pressure can be obtained, especially low frequency is enriched and satisfied.
