Try tapping the AF transistors gently with f.e. the handle of a screwdriver next time it mutes. Martin

Wow, driving around in a 1962 Cadillac, playing finnish tangos, doesn't get any better ! Nice car ! Let me note that the white streaks on the top part of the FM dial are not scratches to the dial but merely ambient light shining down onto the chassis from above, visible through a clear part of the dial where the pointer moves. Normally, with the

Richtoy, I thought you were doing BM6000's ? I never replaced one single prescaler in a BM8000 What were the symptoms, the same as in the BM6000 ? Martin

You will have to dismount the sliders and take them apart. Contact cleaner will not remove anything, only shift the dirt around and in the best of cases it won't add to the mess. The scratching sounds are usually not due to contaminatino of the resistive track inside the potentiometer but oxidation on the metal track next to it and spraying something

Time for the first power up. On the work bench, a couple of voltmeters attached to critical points on the two chassis', one measuring the voltage on the (second) filter/reservoir high voltage capacitor, the other one is on the anode of an output valve. The dial lamps were replaced with new ones, so will tell if that voltage is present. A pair of

Thanks. Yes, I couldn't let that one pass and I'll be happy to tell about the repairs when I get around to doing it. But actually, that was not my primary prize today; I was extremely lucky to win this lot : http://www.lauritz.com/Item/Item.aspx?LanguageId=1&ItemId=1653891 and am happy about two of these, one of them in particular. It's

Hey, what's this ? I just noticed this thread. I'm completely overwhelmed and not quite sure what to say... Thanks doesn't really sound enough. I'm having great fun here at Beoworld.
