I managed to fix the dial mechanism and stopped the rubbing between the dial and mask. I also lined up the dial properly and everything tracks good now.
I re-wired the tweeters per the fix listed here on the forum. Not only were the tweeters out of phase, but the OP transformer leads were reversed. Changing those made a big difference in the sound. Can't wait to get it in the cabinet to hear the true sound.
I am still working on the intermittent in the sub chassis. Seems to only happen as the set warms up within the first 5 min. The sensitivity drops off and then comes back. Normally a .75-1uV signal can be heard with the service monitor hooked directly, so I no the radio is up to snuff. I have swapped tubes around, but I need to dig out other ones from my stash. Work in progress, as I want this right before I call it done.
More to come.
