I have a Univox amp model U65Rn that is in almost unused condition. It has a black faceplate unlike all the other pics of this model I have seen. I am hoping to find out why mine is different and if its rareness makes it more valuable. If not I plan to sell it to someone who intends to use it as an amp. If it is rare or an important peice of Univox history I would prefer to sell it to someone who appreciates it for its uniqueness or its amazing condition. I was told by the previous owner that it was manufactured in 1969 and not after that. I have no idea if this is true information or not, or if it is significant. If you have any information about this amp, its value, a production amount I would love to have it.
