Precautions:

1. Before turning on the power, you must confirm whether the power tube has a large enough heat sink, because it is a Class A power amplifier design, as long as the power tube is always in a strong state, as long as the power tube is turned on, it will start to heat up, I will repeat The radiator must be installed once to power on. If the radiator is not installed, the power tube will explode and smoke. Especially newbies must believe my words-if you do not follow my instructions, you will burst the tube at your own risk (If the tube bursts after receiving the goods, don't find a reason to tell me: I did according to your instructions, I It’s impossible to understand so much, please don’t tell me such things) 2: The power tube must be insulated (the shop did not distribute the insulating pad and the insulating cap when the finished board was distributed) and test whether the two tubes are insulated. If there is no insulation, the same should be burned.
