I am looking to replace a transformer for a rechargeable razor which was
plugged into 220V by accident, not me the kid. It's marked
File:0326-3501-01
I/P 120V O/P 3.8V 110mA
Gooogle showed little and searching Mouser and a couple of others didn't
find anything even close?
Any help is appreciated. I still have to run to the local surplus
electronics store but they are closed today!
Thanks! |

That's not a transformer, it's a power supply with a 120VAC input
and a 3.8VDC output which can supply 110mA into a 34.5 ohm load.
(Your razor.)
What does it look like and how does it connect to your razor?

Looks like a transformer..1" square, red input wires(120v), black
,read out wires, there is nothing else, no diodes, etc...
red input wires go into the top section, red/black come from bottom.
It sits inside the recharger and it's only external parts is this
"transformer" a resistor and a small led to indicate power.......... |

There has to be at least one diode in there, somewhere, in order to
get the DC to charge the battery.
My suggestion is to either get a replacement "transformer" from the
manufacturer or to replace the charger.

You were right under the tape around the windings on the red wire was
one diode! Thanks for the time reading this, now I can find a
"transformer" and add a diode to it. |

Since your power supply states 3.8 VDC out and the diode will drop
about 0.7V, your replacement transfomer's output voltage should be
close to 3.2VRMS with a 110 mA load on it.
Sounds like your razor's got three NiCds in series to run the motor
and nearly a whole day to charge up after you've shorn yourself.

One warning - I had a Remington like that and it used a capacitor in series
with the primary to limit the voltage to the transformer. You'll almost
certainly need to buy the correct part unless you are confident enough to
try to cobble together something with a small audio transformer. In my case
they only sold the charge module complete which ran about $10.
