Zenith 12H090
#34

Another search for info - actually I was looking for operating instructions for the sake of interest - turned up the Nostalgia Air files for this radio. Lots more info, including the simplified schematics which help understand what is in play for the different band selections. I'm really pleased to have this, similar info for my RCA was very helpful in finding out the capacitors which were upsetting oscillator tracking on the SW bands.

I don't hold with furniture that talks.
