Hello everyone,
I am very new to radio restoration and I have run into a problem. I picked up an old Philco 42-390 at an auction recently and decided to try and make it work again. The radio itself is in great condition, but it did have what appeared to me to be the original capacitors. I ordered a capacitor replacement kit for this model and soldered in all of the new capacitors to include the electrolytic. I just plugged the radio in and all I can hear from the speaker is a hum. I am about 99 percent sure I installed the new capacitors correctly. Assuming this is true what should my next steps be? I apologize if something similar has been posted before. Thanks in advance for any help.

Andrew
