I have one of these in my garage patiently waiting for a bit of
restoration magic...

The RCA 811K was a high end console with a very interesting feature.
Seek tuning. Push a button and a 24 vac induction motor tunes the next
station up the dial for you. When it reaches the top of the dial a limit
switch reverses the motor and it seeks down the dial. Hear something you
like? Let go of the button. In case you're wondering how accurately this
can happen, the design features AFC to find center slot for you. (6J7
operating as an 'osc control' tube) Seems a bit ahead of its time for
1937, but if I'm lyin' I'm dyin'... I have never come across another AM
radio like it.
Aside from that it's typical upscale RCA of the vintage. Pair of 6F6's
in push-pull for the audio out, three gang tuning cap with RF amp, three
bands covering AM BCB through 20 MHz, six station presets with cap &
coil tuning, 12" speaker with the big booming sound that sounded so good
in the 60's when Motown was all over the dial. Here's the schema in case
you want to give it the hairy eyeball:

Plus... It's in Dayton. How HamTastic is that ???
