hi D,
It looks more like Brown than Red to me.??
Which part of the circuit is it from.?

As a colour check I have added a Brown and Red bar to your image

You know - It could be brown !

It sits from pin1 (Vcc) of a TBA810S to ground.
It's in an amplifier module from a Polish Transistor Radio - circa 1980.
(Actually the IC is a UL1481P - obsolete) . TBA810 is an equivalent.
This capacitor does not appear in the schematic.

This version of the radio is Mono , with only one Amp ic. The schematic I have refers to the Stereo version. ( same pcb but only one chip).

Thanks.

I was just looking for a complete understanding of the schematic before attempting a repair.

Ah!

I was reading the bands the other way !

It reads a value of 82 n on my meter.

I guess the tolerance on those would accommodate that value.

reading 82 when the bands told me 4100 was just too illogical for me !

Thanks to all.

It reads about 82 nF as I said above.

I've since compared it with other capacitors of the same properties else where in the radio and by checking the schematic, I realise that the bands *are* read from the bottom up. thus it is (Brown or Red) , Black, Yellow = 1 , 0, + 0000 = 100nF . (or 200 if Red)

I guess 80 nf is close enough to 100 :)

Thanks for all your help/comments.
