RCA 816K motor missing. I have posted a photo I found online of someone else's set which has the motor and a photo of the set I am considering as a new project.įile comment: The 816K with the missing motor

I notice also a switch at the end of the variable capacitor appears broken and wonder if that was the reverse sensing switch?ĭoes anyone here have an intimate knowledge of the tuning motor and how it would function? And more importantly how could it be replaced? Is there anything special about the field winding or the construction of the armature? I see the broadcast world history website includes all the RCA Review literature from the 1930's and perhaps I will find something there. It looks like a basic induction motor however it is to reverse at each end of it's travel across the scale. I can fabricate the shield but it is the motor I am concerned about. The only thing (which was a big feature of the set) is that the tuning motor has been removed and the metal shield has been removed. (Although I knew for sure of one cost saving approach that came along later: the AC/DC radios that eliminated power transformers.I was considering the restoration of a 1937 RCA Victor 816K. Interesting, and something I'd suspected/been wondering about-if radios didn't have an evolution that allowed cost savings.

Radios of this time had potted transformers and interstage transformers, chokes, so were more complex/expensive in a way, later circuit designs eliminated them to save cost A number of short wave radio stations, with location and frequency, are marked on the base.

And doing this may just fix problems without having to actually diagnose them. RCA-Victor 'Globe Trotter Radio' Globe 'Globe Trotter' was the catch phrase RCA used to promote its short wave radios beginning in the 1930s, and a globe such as this was probably given away with one of their radios. The thinking is: if the part hasn't failed yet, it probably will fail soon. It seems like most people into radios now just automatically replace any failure prone parts before doing anything else.

This is possibly already known, but this is worth mentioning. 1930’s RCA Radio 150 (sfo > half moon bay) pic hide this posting restore restore this posting. It was initially a wholly owned subsidiary of General Electric (GE) however, in 1932, RCA became an independent company after GE was required to divest its ownership as part of the settlement of a government antitrust suit.

Before you bring up on a variac might be good to replace any suspect capacitors (called condensers at that time) as at least some will probably be leaky unless John or someone else did that already. The RCA Corporation was a major American electronics company, which was founded as the Radio Corporation of America in 1919.
