Yeah this Philco has none in the bakelite blocks.

I have been running the radio hard for a few hours now with good volume and notice there is still distortion when cranked up on a local station yet it sounds fine on distant stations at same volume.
I swear there is some feedback happening somewhere under the chassis. I would hate to give it back like this but the damn thing works perfect except at the most random time. All caps check out, resistors and so on.
Only thing I can figure is the higher AC line voltage used today makes the osc/mixer tube feedback more than originally expected.

I don't know at this point. The radio is playing so great but on strong stations I swear there is distortion on high volume that is not there on distant stations at same volume level with volume control compensated for weak stations.

Also switching the two 6F6 tubes around provides different volume/distortion levels even though both tubes are good. I tried a few different tubes but I am getting fustrated because the circuits itself does not seem consistant more so than the tubes themselves.

Sorry I am rambling.
The radio sounds perfect at regular volume but on strong stations and loud volume I hear distortion. I am thinking it should provide the volume or am I pushing the radio itself beyond the limits of audio amplification?

I got to keep in mind that the speaker will probably sound louder in the cabinet also. So maybe I am hearing distortion on loud volume because I am hearing it at higher volume than meant for w/o the cabinet to reinforce the amplification.
