Hi Dave, Thanks for helping me out. In between posts I checked the voltage at the input to the decoder and to my surprise there is only 4.5V when the voltage (without load or decoder) is 17V. So there must be something wrong with my decoder. The question is where?

About the LED flicker this goes out when the mono/stereo switch is shorted - the LED remains on all the time. Meanwhile I have disconnected the decoder from the supply and took my output from the cathode of V5b.

Again there is one station clearly audible but then a lot of other stations coming in (more like noise). As before, tuning to different frequencies does not change the signals coming in. So now it seems the problem is originating from the tuner.
