Hello - I am new to posting in Forums but, I recently got a 1964 Magnavox astrosonic from my Grandmother and noticed the left channel has no sound. I used the contract cleaner and the right side has gotten a lot louder/clearer but there was no difference on the left side. When I turn the volume all the way up with the right channel disconnected, I can hear a faint signal coming through the left channel. Can anyone help with this issue? I am a little hesitant to take out the electronics to check if the capacitors are blown as this is a family heirloom - Any help is appreciated
