The PHILCO Phorum

Don't think I'll change anything since I have other much better radios to listen to.  Now that I know why it's there and that it's normal,  I'll live with it.  It's for show anyway.  I notice the same kind of distortion in the 80 Jr. but didn't really expect much from that radio, though it surprised me. I expected better from the 70.  Oh well.

Same distortion will exist in 20, 50, 70, 90.
80jr I believe employs grid leak detector.
I don't remember how it sounds though I do have one, I don't listen to it much as it is, well, 80jr and not much could be expected from it.

Yep. (see post #2)

Yup. Welcome to my world, Russ. I feel your pain.
