Switch Power Supply Transformer with Aluminum Alloy Heat Dissipation Cover for Electronic Tube Single-ended Preamplifier

Switch Power Supply Transformer with Aluminum Alloy Heat Dissipation Cover for Electronic Tube Single-ended Preamplifier

Description:
- The high-voltage output adopts synchronous rectification technology and delay function, which can delay for about 30 seconds to avoid the impact on the tube when the filament is not hot. (Science popularization: In the past, using an electronic tube rectifier for rectification, electrons were slowly emitted after the filament was lit up, and the high voltage also gradually increased, which had a very small impact on the subsequent electronic tubes and could significantly prolong the lifespan of the electronic tube. Therefore, this power supply is also designed to slowly increase the high voltage from 0V to 280V, rather than using it to delay the circuit time. Suddenly applying high voltage to the electronic tube can maximize the lifespan of the electronic tube.)

- In order to achieve better results and quality, the filtering electrolytic capacitors of this power supply are not individually purchased, but all new long-life capacitors are purchased, with a service life four times that of ordinary capacitors. High power high-frequency transformer with copper tape shielding layer, allowing your machine to have less interference and lower background noise.

- The bottom noise is clean, the treble is clear, and the mid-range is rounded, which solves the problem of the original electronic tube lacking bass and makes your machine's bass more powerful. It is especially suitable for the front stage of electronic tubes, ear amplifiers and the small single end. It has achieved the effect of a push-pull machine for ordinary small single end devices such as the 6P1, and is even better than it, allowing your old machine to regain its vitality.

- This power supply is suitable for 6P1; 6P14; 6P15; 6V6; 6P6P; 6L6; FU32 and other small single end applications. When using the power supply, it should be tightly fixed against the chassis and can be assisted in heat dissipation through the chassis. The chassis should be well ventilated and should not be placed in a sealed shell. Normal use below 60W, enhanced heat dissipation above 60W.
