bakelite blocks philco 37-630
#4

Well guy's, It looks to me like someone added a block down at the bottom or back side of the chassis.
Nothing shown there on the parts list diagram.
THe power cord is supposed to be wired to the block that is shown on the parts list diagram.
Looks like they added a second block and wired the power cord to that one.
They also did some jerry rigging when they replaced the electrolitics.
Anyway, I replaced the double caps in both blocks and still have the slight distortion.
In fact I now have a squeal if I turn it all the way up on the volume.
THere are a couple caps I could still replace if I dig enough.
Seems to pick up lots of stations, just has a distortion problem.
Tested all tubes and replaced a couple with no luck.
Tried adjusting the alignment a little, but no luck.
Any suggestions from the experts?
Thanks and have a great weekend.
