Free stuff could perhaps be in a separate sub forum, but I don't see a real need. Spare parts and non functional or defective items offered for sale could just carry on being put on 'Private Exhibitions' as per normal as has been done previously. There were free cables in the last day or so and components parts are offered too.
I think the main question was whether free stuff and spares should be offered. Well they have been, without problems.
It is impossible for anything digital to sound analogue, because it isn't analogue!
