That's exactly what we did, change the plugs. I've just spent the morning round at my friends house having a first look at the kit. I'm pleased to say it all looks in much better shape cosmetically than I was expecting from her photos and description.
We hooked up the Beogram 7000 and RL 6000 speakers to the Beocenter 9300, changed the batteries in the remote control, plugged in the Beocenter, propped up the speakers on the back of the sofa, and switched the power on. There was no smoke or strange noises, and all the right lights seemed to come on. Using the touch controls we managed to play a CD, a cassette tape and listen to BBC Radio 2,3 and 4 with no aerial. The sound wasn't bad at all, quite good in fact, given that we only had the speakers propped up on a sofa and made no attempt to adjust any of the sound settings apart from volume.
We didn't have quite the same luck with the Beogram 7000 record deck. It all seemed to be working ok insofar as the turntable went round, the stylus dropped onto the record, and the arm moved tangentially across the record, but the sound was very fuzzy and distorted. My first thought was that there was something wrong with the cartridge/stylus. However, based on a purely visual inspection with the naked eye there was nothing obviously wrong with it, i.e no dirt clogging the stylus or bent cantilever, and my friend says that she played some records when she was clearing out her Dad's house and it was ok prior to being boxed up and brought back to the UK. Assuming it's not the cartridge - and that's by no means certain at this stage- I'm wondering what else it could be? Unlike a conventional turntable there does seem to be much the end user can do except adjust tracking weight. One thing that bothers me slightly is that the turntable was brought back without the transport screws being tightened, though the suspension seems to be o.k. Anyone who knows these decks got any ideas?
Also does anyone know how to store tuner station settings? We can get it to search, but when we try to store the setting , it tells us it's stored but it's not not there when we try to re-select it. The manual we've downloaded isn't very helpful as it doesn't seem to cover tuner setting at all. We must be doing something wrong?
