    I am trying to fix a amplifier, but I stumbled upon a diode which I cannot identify.

    On the diode:
    10E
    N
    06

    I am not getting wiser on Google, so maybe anyone knows what diode this is?

    Need more clues. What century was this amplifier made in? Does it have vacuum tubes? Is the diode in the form of a resistor? A bolt? A piece of glass? A piece of black plastic?

    It is a Sony TA-F220. Build year 1991. :) 2015-08-28 20.15.44.jpg

    My first thought would be a 10A 60V Shottky barrier - but that picture looks no more than 3A tops, and you don't often find SB rectifiers in amplifiers.

    Its got a vaguely Sanken look about it - but that's purely a guess.

    A photo of the circuit board might show us whether it's in the power supply area and can be replaced with a 1N4007 or some other garden variety 10 cent part.

    Audio amp. 80 watts into 4 ohms. Very likely it's a common part.

    I'd say the picture looks more like a 3A part. 1N540x variety perhaps.

    Well I checked the schematic, couldnot find it. So after some more googling I find another (the same, but different) service manual (taf120.pdf).
    The diode is located at the switch board for the speakers impedance. C623 and C622 are shorted, but it is not on the parts list. So I checked the other diodes, they have a threshold value of 0.60 Volt. Can I just replace it with a 1N4148?

    Without some sort of scale alongside the device in the photo, its only a guess at the physical size. But I'd say i looks like at least a 3A device - a 1n4148 might last a few microseconds!

    The 06 in the device number is more likely to indicate 60V (if so, it could well be a Shottky-barrier) - but without any hint at who the manufacturer is, its impossible to look up their marking conventions, and unwise to make any sweeping assumptions.

    The diode is on the input power supply rectifier based on taf120.pdf. It looks like full trafo secondary voltage is used with 8 ohm speaker setting and reduced voltage with 4 ohm. Fuses on "4 ohm circuit" are 5 or 6.3 A time lag so diode has to be high amp rating too. If 0.6 volt is measured on healthy diode it indicates typical silicon rectifier diode. Diode amp rating has to be high and rating can be estimated from the sice of the existing diode. If it looks to be at least 3A on the picture perhaps 3-10 A is suitable. But it can be typical rectifier diode, not fast diode.

    The dimensions of the diode: diameter=2.7mm and length=5mm
    I have a FR105 diode, same size and is 600V diode, but measuring a threshold of a little over 500mV. But the diode has a maximum current of 1A. I think I will give it a try, i do not have anything else at the moment.
