Condition:New
Type:Logic ICs
Introduced 2021 new high-power EL34 tube tube amplifier power amplifier kit.
Advantages of this kit:
1. Develop a new laser cutting, electrostatic spray case (two-color optional)
2.5 electronic tube installation positions, support adapter board, adapt to various circuits, easy to upgrade in the future.
3. Double vu meter design, and the lining structure is adopted to prevent the meter head from protruding.
4. Independent volume control for the left and right channels to avoid the volume difference caused by the wiring of the circuit.
5. Reproduce the circuit designed by Japanese enthusiasts, the circuit design is reasonable, and the sound quality is good.
6. The components are all imported components, Seiko capacitors from Japan, high-quality 5-color ring metal film resistors from Taiwan, and Weimar coupling capacitors from Germany.
7. Large-capacity inductance filter, the sound is more pure
Electronic tube composition structure
As long as the buyer makes the finished product according to the physical map we issued, there is basically no noise and hum.
Rectified by 5Z3P, the front stage promotes Sugon 6N9P (or 6H9C imported from the Soviet Union) power tube adopts Sugon or EL34-B
The machine power is 20w (2x10w), which is equivalent to about 80w~120w thrust of the transistor stone machine. Regarding whether your speakers can be promoted: It is related to the room size and personal listening volume preference.
Regarding the power level, and whether it can promote your speakers:
The power of the single-ended amplifier of the tube amplifier is generally 3W-30W (common), because it works in the Class A state, the load capacity is stronger than that of the transistor, so a few watts of power can still drive the speaker (except for speakers with low sensitivity). The demo video is a pair of 2x150w dual 6.5-inch floor speakers. The room is more than 20 square meters and the volume is 45%, which is already very loud!
The amplifier should be equipped with speakers and the effect is very good. EL34 has a mellow and natural tone, mellow sound bottom, sweet and warm, especially when listening to human voices, it is very rich, transparent and durable. It is more suitable for listening to human voices, piano sounds, strings, guzheng, etc.

Precautions:
1. Tube DIY requires certain basic knowledge. Our shop will also provide circuit drawings, physical scaffolding drawings and a full range of technical support services. As long as you are careful and patient, you can succeed.
2. This tube amplifier does not contain power cord and audio cable, because the quality of this product is uneven, and each buyer's requirements are different, so we recommend that customers match it by themselves.
3. This machine does not have Bluetooth module. If you need a Bluetooth module, you can also contact the seller to send a payment link, the price is $20.Bluetooth module is external connected.
