Bitte Hilfe: UHER SG 520 Variocord :)

[kaimex]

Hi Andrew,

you can find the schematic of the SG520 at
http://tonbandwelt.magnetofon.de/uher/var520s/var.htm

the service manual as a collection of single page scans at
http://wegavision.pytalhost.com/Uher/UherSG520s/

The schematic shows only the tape-end switch K4 in series with the mains fuse.
There is no indication how the switch is actuated.

Regards
Kai
