Grundig Radio help

[sloober]

I did not, but was considering doing so. They all have a chalky white stuff at the ends and I'm not sure if it is just old, or actually falling apart. I did hook a cap meter to several and they do show capacitance close to their makings, but I am not checking for leakage. My general rule is to shotgun all the old caps, but this one is tight and will take some time. I guess I will start with the coupling caps and go from there. John

thats it for sure, guarantee. forget the cap test, they leak at voltage, you can confirm by reading the bias of the tubes, but why bother they leak. I would not turn it on again, least you risk red plating the tubes.

Those ero caps are all junk. you'll never find a good one. Replace them all with quality mylars and troubles will be gone. Even if you find a grundig or other german radio that seems work ok and it still has those caps, get rid of them anyway. You'll be rewarded with even better performance.
