Thats what I did the other days. Attached some pics of both pads. Its felt, but with some black coating on top that gets off quite easily. I first thought it was dirt... These brake pads are not even shown in the exploded views in the service manual! No part number. Strange, they seem to be a maintenance item as they clearly wear out.
Result of the swap was a decently working VCR, but I'm not sure whether that is due to the brakes or if there was something else. I now notice that the pads do indeed not touch the takeup reel in play-mode. Couple seems quite OK. I do not have a torque gauge, but when I hold it with my fingers it feels reasonable. Is there a quick-and-dirty method to check whether torque is in the required range?
The other VCR, the one that seemed to smoke a joint, is working happily since. I still have no idea about what could have caused it. Eventually one of the zillions of electrolytics went bad somewhere in a circuit I do not use when playing Secam to PAL...? Power rails are all good, so if it was an electrolytic it either went open circuit or it shorted out and charred a series resistor or a part of the printed circuit.
Does anybody know if there is a way to access the parts that are hidden by the RCA sockets on the output board? I couldn't figure out a way to remove the plate holding the sockets from the board except by desoldering all of them. Most of the remaining smell came from underneath that plate, but I couldn't see anything wrong looking between the boards from the sides.
