I’m attempting to refurbish a Remington Electric Shaver (circa 1940). This is identified as Model P and operates on 110 VAC or (TBD) VDC. I’d appreciate any insight. I don’t have a schematic and am assuming the brownish area in the photo is (or used to be….) a capacitor. The shaver’ jumps’ once when I apply 110 VAC, but then nothing.

 

...or (TBD) VDC.

I'd be very surprised if that ran on DC.

 

It's listed as a dual voltage shaver, but it's certainly not obvious from the (few) parts inside, how it would work on DC. I've seen 1940s newspaper ads showing men using the shaver in their cars - I'm wondering whether the DC cord actually included a DC / AC inverter.

I changed my mind. There's a set of contacts that make/break DC to the coil (which is just a solenoid):



First step: clean the contacts.

If that doesn't work, there's likely a rectifier to convert AC to DC (or just pass DC). Look there for your problem.

 

Looks like a burnt capacitor to me: https://www.tubeampdoctor.com/en/tad-silver-mica-caps

 

It would appear that the contacts should be opening when power is applied to the solenoid coil, and for some mechanical reason they are not. .

They're probably welded.

 

There's a dial on the front of the shaver - with power removed, I can spin the dial and watch the off-balance cam in the shaver rotate and open / close the contacts. When I apply power, nothing happens unless I find the very narrow sweet spot on the dial where the shaver tries to operate, but can't sustain it. I'm leaning towards the reply above suggesting a bad capacitor - I'm going to replace that and see how things improve (or not...).

 

Hello Kevin - I have the same problem with an old Remington Shaver as you have described. I would really like to know if you were able to resolve the problem and what other issues might have needed solving. My shaver is a Model W, Triple Head - mid 1940s. thanks much, Ron
