Uher 4400 Report Monitor noise problem
Happy to report that I now have an English language user manual and some circuit diagrams on a CD-ROM bought from a UK eBay seller. Having got it functioning fairly well after cleaning the heads and the pinch-roller (all filthy) I find that I have a noise problem on the left channel (a low hum) and also no response from the needle in the left channel meter. Does anybody have any experience of this and any putative causes?
