![Icon_redface Icon_redface](https://philcoradio.com/phorum/images/smilies/icon_redface.gif) Oops, can't believe I misread that.. And the tube number. Wow. Swapping it, and resoldering the grid cap of the old one fixed the noise. Thanks!
This morning it was oscillating very poorly, and died every time it was tuned through 850-900. I decided to redo the coil again. This time it came out perfect, exactly the way I wanted to do it in the first place. Put it back in, and I'm back to square one... ![Icon_mad Icon_mad](https://philcoradio.com/phorum/images/smilies/icon_mad.gif) Nothing below 1200 this time. The last possibility in my mind is that Radio Daze used bags with some sort of ESD protective material that is messing with the feedback.
From other people who have had success, what is the best substrate to use between the windings? I've also tried teflon tape, which sort of worked, but made a good winding nearly impossible.
