For some time I tried to obtain a reasonable FM reception on this set.

I replaced all the tubes of the FM part,I adjusted everything according to the sevice manual but the

reception is pretty poor,on many stations there is a annoying background noise like there is a problem with

the tuning of the hf stage.
