Thank you for visiting our shop.
I wish you a happy life.
EL34B introduction: The output power is greater than 35W. EL34 is similar to 6CA7 and can be used interchangeably.
The difference between EL34A and EL34B: Shuguang's EL34 has two tube types: EL34A and EL34-B. EL34A adopts control grid and accelerating pole (g2) misaligned grid structure and belongs to pentode. EL34-B is the accurate grid of g1 and g2. It belongs to a beam tetrode, which is suitable for manufacturing power amplifiers with moderate power. It is also suitable for super linear circuits. The board consumption of EL34A is 25W, and the board consumption of EL34-B can reach 30W. Compared with KT88 , EL34B's sound is more delicate and sweet and expressive.
EL34 high-performance audio output pentode, its anode plate has a limited dissipation power of 25W. In the audio amplifier, the output power is greater than 10W when the single tube is used for class A1 amplification, and the output power is greater than 35W when the double tube is used for class AB1 amplification. EL34 is similar to 6CA7 and can be used interchangeably.
Regarding matching:
all our tubes are matched in the factory production workshop. The match is accurate (not all tubes are matched). We have the conditions and advantages to match multiple tubes (four, eight, ten) according to customer needs. The parameters of the two tubes are the same)
Buy 2 pieces, 4 pieces, 8 pieces = exact matching (matching group). No parameter drift.
Note: (After receiving the tube, please do not think it is a fake or shoddy product). Quality guarantee for one year.
