No – as long as it matches the output impedance of the amplifier that it’s plugged into. In a valve amplifier the output transformer’s windings
High voltage safety guide
All assembly and testing and tweaking of electrically powered equipment should be done with care. Mains voltages (100-240 Volts AC) themselves are dangerous and almost
What about speaker ratings?
I always recommend running within the rated power rating of your speakers. So, if I am using an 18W amplifier, I do not run it
