考虑综合性因素，纠结陶瓷管的风噪，又却步玻璃管的价格，陶瓷管没实际使用过，风噪到底能接受不？放在桌面上的话，有问题吗？

@"BD3VY"#p92398 电子管功放鼓风机是一直工作的，离电台很近或者堆在一起使用的话会很吵。

开台前还要预热半小时，体积也蛮大的，但觉不适合桌面使用

电子管乌龟开机预热几分钟，关机散热几分钟，工作时风扇会一直嗡嗡的转，冬天的时候可以取暖，听习惯了反正比底噪好容易接受，时间久了耳朵也就自动屏蔽那种声音了，关机后，会觉得瞬间周围都安静了许多，个人建议入手个大于1000W的。

个人经验戴上耳机，风扇噪声基本就可以忽略了，外放的话还是有点影响的。不过某种意义上来说，搞1kW的功放，电台那边怎么也得需要大几十W的功率去推，电台本身也会有风扇散热，那个声音不影响的话其实功放的风扇声音就也还行

为啥要功放？五六百瓦的还是放弃吧，因为我有个电子管的FL2100B。但是现在这环境，千瓦是平常的。

电子管呢开大一点功率就谐波大而且死沉，好处是冬天用省了暖气，而且不贵，想体验大功率快感用电子管挺好，想效果好还得固态

I've been feeling a bit restless lately and I'm thinking about buying a tube amplifier. Do you have any recommendations?

Considering various factors, I'm torn between the noise from ceramic pipes and the price of glass pipes. I haven't actually used ceramic pipes before, so is the noise acceptable? And if I place it on a desk, will there be any problems?

BD3VY The fan for the tube amplifier is always running, and if it's located close to a radio or used in a cluttered environment, it can be quite noisy.

It also needs to be preheated for half an hour before use, and it's quite large in size, but I don't think it's suitable for desktop use.

The tube amplifier needs a few minutes to warm up before turning on, and a few minutes to cool down after turning off. During operation, the fan will constantly hum. In winter, it can also be used for heating. Once you get used to it, it's much better than background noise, and over time, your ears will automatically filter out that sound. After shutting down, you'll feel like there's a sudden increase in silence around you. I recommend getting one with a power rating of more than 1000W.

Based on my personal experience, with headphones, the fan noise is largely negligible. However, when playing audio through speakers, there's still some impact. But, in a sense, achieving 1kW of power requires a radio to output at least tens of watts, and the radio itself also has a fan for cooling, so if the fan noise doesn't affect the sound, then the amplifier's fan noise is also acceptable.

Why would I need a power amplifier? Five to six hundred watts is probably overkill, since I already have an electronic tube FL2100B. However, in this environment, one thousand watts is quite common.

BH7JUO

As for vacuum tubes, increasing the power output results in larger harmonics and a "dead" sound. However, they are relatively inexpensive and can save on heating costs during winter. If you want to experience high power without breaking the bank, vacuum tube amplifiers are a good option. For better performance, solid-state amplifiers are preferred.

陶瓷管肯定是有风噪的但可以把电台的声音开大一点点第二尽量不要选那种用小风扇做鼓风机的功放那个非常吵如果实在不想吵就搞个玻璃管的功放

BH9FTJ

我自己做的陶瓷馆风扇用的1600rpm的感觉还可以接收那种小风扇的2000多就太吵了

请教一下，电子管功放，电子管的寿命一般多久？
