but not of the power supply + amplifier unit alone when it is in dismantled condition. This images I have upload here.
To remove this unit from this device, numerous steps must be observed that are not described in detail in the service manual - go to

Therefore it was very difficult for me, among other things due numerous cables that have to be unsoldered and because of the very tight space available.
With the help of a second device of the same model, I succeeded.
After removing some contact issues at the variable resistors and assemble of the PS/amp unit there was at both devices still to observe a more or less effective contact resistance in the signal path (variation of output level similar like on a defektive volume control pot - both on FM and AM-ranges).
After long search I note, reason therefore is a crack of conductor track (at both devices of this model) between 15m and 19a of StV301 (push-button switch assembly.
To avoid dismantling the entire device (to get to the soldering side of the main board), a cable connection was simply soldered between the soldering connections 15m and 19a of StV301.
Are there anywhere pictures on the web from a completely dismantled device of this model and the associated steps of this process ?
Best thanks for posting an URL.
