Well, after taking out the RF section, replacing some caps and putting the set back together, all H**l has broken loose. Prior to taking out the floating RF, I was getting great reception and volume across all bands. Now, I am getting very weak AM volume and somewhat decent volume (though there's a lot of squealing going on) on the other bands. In AM, I can barely hear it with volume turned all the way up.
When I squeeze the 6A8 Dector/oscillator grid cap wire, the volume increases a good bit. In SW bands, it's very loud, just about what it was before, I think. In AM, its loud though not as loud as it was prior to pulling out the RF section. When I let go of the grid cap wire, the volume dies again. Reception is poor on AM; on the shortwave bands, there is some reception; however there's also a ton of squealing. The 6A8 voltages are pretty much where they should be. Tubes all test good.
Can someone guide me through some troubleshooting? I would love to solve these issues. It's a beautiful set and I'm very discouraged. Could use some expert help.
Thank you.
Here's a clean copy of the schematic. Click on the photo once or twice to zoom all the way in.
