Hello Ken,
the ebay offer seems to come from the Swiss partner of SDS-consult.
They have a long list of spare parts that are still available for those Uher portable tape recorders.
Another company offering repair service for Uher tape recorders is
http://www.uher-reparatur.com/
I guess, the micro switch on the fotograph is K4 in the schematic.
The service manual explains its function on page 28 in section 4.1.3 in German and on page 29 in English.
You might try manually whether setting it to the opposite state during/before start eliminates the observed buzzing sound or whether these are two non-related problems.
You could ask the two companies named above (there may be more) for the micro switch.
The SDS-consult price-list contains an item called 1030032 "micro switch diverse" on page 3.
On the other hand, I think that such switches are still produced somewhere, but I can't tell, where to get them.
Regards Kai
