This came with one of my 2nd gen recorders, I am not sure which, but I assume the earlier DCC300. Was someone such a big Philips fan to glue this, did it come from the factory like this at some point or is it some sort of prototype?
I was not able to find anything like this on the internet, that’s why I am asking.
@drdcc If this is relevant for the museum I will consider donating.
More to come on the subject of infrared, stay tuned.
