I’m currently working on my Philco 40-180 radio. I’m having an issue. No sound. Low hum from speaker. I keep smoking (60) resistor. My voltage across the (61) capacitor is 200VDC and the voltage across (58) capacitor is around 40VDC. Not sure what’s going on. I appreciate all the help this is my first radio and I only have a basic knowledge of electronics. Thank you
