philco 37-630
#1

Have been working on a 37-630 console that I picked up.
Someone has replaced the electrolitics recently.
No audio when I got it.
Found the output tranny on the speaker to be bad.
Bought a replacement speaker with tranny on ebay.
That took care of the audio problem, but it is distorted at lower volume. sounds better at higher volume.
Seems to get more distortion as it warms up for a while.
Have replaced a bunch of caps and a few resistors, checked the tubes.
Any chance the tranny on the new speaker is ok, but the voice coil is weak
Have not replaced any of the caps in the bakelight blocks yet.
I know some of the tubes checked barely in the green zone.
Which tube would have this effect on the am band?
Thanks and hope you guy's have a great weekend.
