AIYIMA SMSL 6G2P 6SQ7 Push 6p13p 6N13N 6W 2.0 Dual Vacuum Tube Power Amplifier 6z4 Rectifier Class A Point to Point Soldering Amplifier Audio
6G2P-6P13P Class A point-to-point welding machine parameters:
Output power: 6w+6w (dual channel)
Output impedance: 8 ohms (4 ohm wires are reserved in the machine)
Frequency response: 20hz-25khz
Input impedance: 100k
Signal-to-noise ratio: 89db
Input sensitivity: 400mv-2V
Harmonic Distortion: 3%
Overall volume:
Width 260mm Depth 230mm Height 170mm
Tube for tube:
Rectifier tubes: 2 6z4 tubes, 6u4n 6x4 ez90, etc.
Pre-stage tube: 2 6G2P tubes, there are 6 factories 2 6SQ7 etc.
Post-stage electronic tubes: 2 6p13p tubes, 6n13n and so on for replacement tubes
New dual-tube 6z4 rectifier, 6G2P-6p13p single-ended Class A 6W+6W dual-channel power amplifier launched
The machine uses dual-tube rectification, and two 6z4s in parallel can output 150ma current, which is enough for 13p tubes. The pre-stage is driven by a high-amplification 6G2P tube. The post-stage uses 6p13p for power amplification.
Pure copper crystal terminals are used on the back of the machine. 8 ohm output by default
The whole machine adopts point-to-point welding method, pure copper leg metal film resistors, new Philips filter capacitors, Taiwan stepper potentiometers
The recommended speaker selection parameters are as follows:
1: The machine is suitable for 15 to 60w. The sensitivity must be above 89db, 90db is better and easier to push (such as 89db±3db)
2: Speaker diameter: 2 inches to 8 inches full frequency or 2 frequency can be.
3: The speaker impedance is suitable, 4-5-6-8 ohms can be used.
One machine is shipped by default. 6 tubes. Randomly send a national standard power cord.
Notes are as follows:
1: The real tube amplifier must be connected to the speaker before it can be turned on. In any case, it cannot be empty, otherwise the tube and transformer will be burned.
2: The tube amplifier can only push a pair of passive speakers, not active speakers or subwoofers.
3: The socket used for the amp can not be shared with the computer, TV and fan. It is best to separate it to prevent electrical interference from noise.
