I think maybe it's time for some detective work and start asking questions, I would bet that someone too it to use as a tube amp and that it still exists somewhere. Either that or the caps shorted and the transformer did a smoke show so they pulled the sub chassis for repairs. As for the clock I'm guessing that it may be an off the shelf electric unit adapted to use in the Rogers, it may be similar to the ones used by Motorolla and G.E in the U.S. G.E was the largest maker of electric clocks through the Telechron Company so if Rogers used a Telechron clock there could be a similar movement used in a desk clock. Needless to say for $25 you can afford to put some money out to get the proper parts.
