Amplifier Burned 🔥? YL Raisa looks inside R-140
There was no smoke. But the smell was all over the Shack. I was very scared and immediately turned everything off. I opened my Power Amplifier R-140 to explore its insides and to show to a specialist online. Fortunately, Ham Radio works also by low power and even QRP, especially when the good antenna and the active Sun help! ;-) -- My other social media with Ham content: / ylraisa / ylraisa 73&88 and see you On the Air!
