Title says it all: i've replugged, after several years of storage, the 4dd10 decoder and... it works, as usual, on demodulating cd4 records, but when there is no 30K carrier it does a lot of noise (white). Run-in and run-out grooves are without carrier, so it does quite a mess before the music start or after the end.
What can be?
