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.
For unbalanced output and conversion of balanced input

Center tap is on both sides, it is handy for ham sound protection.
Audio amplifier's driver transformer

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

On line with rich line-ups, it's cheaper than any dealer. This is a bargain.
Production of small output semiconductor amplifier for audio
On 2017-08-25 22:37:31
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

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

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.
Step-up transformer for piezoelectric ceramics

It is compact, lightweight and perfect for mobile purposes. The price is also worth it.
Production of tube amp
On 2017-04-11 16:32:09
When I made a low voltage tube preamplifier for SRPP I heard a surprisingly good sound (12V, Ip = 0.04mA), so I thought that this transformer was going to be in this format, and that this transformer was better than ten A Because it was scattered, I made it here (it seems to be a standard). For the time being, I tried it with barracks, but because it is SRPP, there was no DC magnetization, so it was a good sound quality out of low range well even without returning. I am surprised at this size. However, it is just thinking that the volume is small and it is impossible to drive a power amplifier at low voltage drive. If you have tried similar things, please teach me m (__) m

It is the best transformer for the ground loop of audio signal
On 2016-10-24 16:09:29
Since the sound of the liquid crystal television was poor, it was connected so as to be able to output both with the external amplifier, but since the output is small and the noise is conspicuous when raising the volume of the amplifier, the output could be raised by sandwiching this product It was. The price was also cheap, so I arrived early so I am very satisfied.

In order to increase the output of the microphone, it was incorporated as an input transformer. The effect was satisfactory and the best one.
Used for impedance conversion of homebrew AMP.

It is compact and perfect for printed circuit boards.

AUX input For volume up
On 2015-07-12 21:00:24
I bought two for the volume up when listening to music by connecting from the smartphone to the external input terminal of the car audio
Used for intercom

It is very good. It is saved if there is more stock.
Impedance matching between car navigation system and PC speaker
On 2015-03-10 20:19:30
Since the sound of the portable car navigation system is small and the music is not stereo, I used it in conjunction with a small PC speaker to connect it directly to the earphone jack, but the noise from the PC speaker was concerned and the sound did not become big enough as expected So I used this transformer as a matching transformer. As a result, noises disappeared and the volume can be secured sufficiently.
On 2015-02-22 20:55:16
Since the product of this time was used to change the impedance, there are no improvement points etc.

Because it is hard to get at home center, thank you for the assortment
