Hello dear community!
I have the following problem with my amp:
The temperature sensor that is supposed to cool the circuit board is defective. According to the label, the fan has a rated operating voltage of 48 volts, but the fan turns up when it is switched on, even when the amplifier is cold.
I then measured it with a voltmeter and found 80 volts, which would definitely lead to the cooler dying in the long term.
I then looked around and have the problem that I have to travel a long way to get the amp to a technician. Many technicians in the neighbourhood wave me off, as hardly anyone knows these amps and wants to make modifications.
Now I have a question for you: I would like to install a separate cooler control, i.e. a 12-volt power supply with a temperature controller that can control a cooler if the temperature reaches a certain value. My problem is that I don't know exactly what temperatures prevail in these amplifiers.
Other modifications have already been made to the amp, including replacing the UV lamp with an LED strip that provides the fluorescent light on the front panel of the amp. I'm already using a 5-volt DC voltage converter for this task, but I don't think it will be enough for cooling. However, even with the 12-volt voltage converters, I'm not sure whether the cooling capacity is sufficient for this model.
Or do I also need to consider a 24-volt fan to maintain the necessary core temperature in the amplifier to prevent overheating?
I also wanted to ask if anyone has any experience with this and can tell me whether it might be possible to find a voltage regulator that includes a voltage converter so that I don't have to accommodate two additional components in the amplifier.
Many thanks and best regards,
Andy
