DIY Electronic Kits for Adults Biliary Electronic Tube Diy Kit Power Amplifier Board Welding Parts Self Assembly Components

Specification:

Item name: Biliary Electronic Tube Diy Kit

Board size: 75*77mm

Shell size: 97*90*35mm

Working voltage: single AC 12V, power supply, current requirement 800MA, AC 12V through rectifier filter

Wave voltage doubling circuit, output positive and negative 28V dual power supply to power the electronic tube.

Signal processing part: the signal is buffered and amplified by electronic tube 6J1 (62), and used by power amplifier or ear amplifier.

The signal is a voltage signal and cannot directly drive the horn or headset.

Product description:

This circuit is designed based on the circuit principle of the music fax X-10D, which has been reasonably optimized and has more stable performance than the original machine. The electronic tube performance has been improved by 10% The main function is to improve and enhance the sound quality, remove the harsh digital taste in the sound source, and make the music sound more soft and sweet. The bile machine has its unique "bile flavor", which can make the sound warm and durable to listen to, with a good sense of music and a good atmosphere. Its significant advantages are natural concern for sound, large dynamic range, and good linearity. The combination of the gallbladder and the amplifier not only has the soft, sweet, quiet, and transparent characteristics of the amplifier, but also gives the music a strong gallbladder flavor based on it, making its music feel better and more durable to listen to, and the overall atmosphere and dynamic range are also better. It is a very worthwhile circuit for enthusiasts to play with.

Note: It's diy kits. Need to solder by yourself.

The audio cable and shell are optional, you can choose to purchase according to your requirement.
Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
Please allow slight dimension difference due to different manual measurement.

Production precautions

1. The power input of this product is a single AC 12V, and the voltage can be changed by oneself. However, the withstand voltage value of the capacitor also needs to be changed, and DC power supplies with DC cannot be used;

2. Do not weld for too long, 1-3 seconds, otherwise the copper sheet will fall off. If it is not welded properly at once, remove the soldering iron and weld again. Be sure to take good care of the production pictures and text, distinguish the positive and negative poles, and pay attention to the white silk screen welding of the corresponding components during welding. After welding, cut all the extra pins to avoid malfunctions.

3. Both input and output interfaces are lotus shaped, and if you want to connect to a 3.5mm headphone jack, you can buy an adapter cable;

4. The knob can adjust both the volume and the switch of the product. Turning it clockwise can power on and increase the volume;

5. This product is a front stage operational amplifier and cannot be directly connected to the speaker. A rear stage operational amplifier needs to be connected.
