Old russian diode recognition.

Hi.
I'm making a stereo amplifier I stoped at diode bridge.
I got some diodes from old russian TV, but I can't find out their polarity.
[my multimeter have broke down ]

Thanks.

Hi,

You have an LED around? Use the diode and LED in the circuit. The LED only lights when the diode is connect with it's polarity one way.

I dont know the current rating, but a small flashlight bulb might work too.

A battery, a coil of wire and a compass.
