Grundig 1070

Hi, trying to get my grundig 1070 up and running. Tubes are lit up and test ok. It is making a loud hum and not receiving, any suggestions on how to proceed?

The loud hum is being caused by open electrolytics. With those open, the radio won't even think of playing, as most of the voltage is ac, due to open filter.

Replace the electrolytics, and, it should help alot.

Hi Bill, I have a bad ECC85. The unit checks out on a bulb limiter, no shorts. Still think it could also be caps? Getting the chassis out any tip so I don't screw up the channel finder

thanks A

I think you'd better ask some of the other guys. I haven't touched a German radio in years, and, honestly, I think they are a nightmare to work on.
