(16 transistors) (50, 50 10 amp) (weight 10 kg+) I built this amplifier as a hobby in 2021. There is a slight layer of dust on top which will make it look brand new once cleaned. I do not have speakers so it is not played anymore, and I no longer have the hobby. The amplifier is fully okay, you can test and check the sound, it is fully clear. Please call or WhatsApp014XXXXXXXX
