Radiola 28 (DC)

[Winky Dink]

The Radiola 28 went operational yesterday. With eight pricey tubes at risk, I was a bit skittish about the power supply connections. Dave Snow at Antique Radios Inc. was very helpful.
Reception is good, but the audio quality is poor. The volume rheostat is a component for AC operation and it only works on very weak stations, so I put a 1Meg pot on the speaker. When I get some idea of specs for the original DC rheostat, then I'll work on replacing it. There are also a couple of condensers missing from the 90-volt and 45-volt lines (B voltages).

This is a 40-second video of the set's on-bench premiere. This is the best audio I can get so far.

And some pictures (I feel like I'm showing pictures of the grandkids to roomful of strangers).

The next project is finding an antenna or building a replica. My woodworking friend who replaced the feet for me is eager to work on antenna. I'm hoping to find someone with an antenna to get some detailed photos and dimensions.
