Zenith R600 TO garbled reception
#6

So, here's what resolved the problem. The filament voltage of the 1L6 was 1.2 volts so I brought it up to 1.43 volts. This helped but not totally. I also went back in to the band switches with cleaner and got better reception. And lastly, I replaced the RF amp tube. The original must have been on the edge(aren't we all?).

Thanks for the suggestions. They got me back to re-checking my work. Rod
