Aaaah! The one piece I absolutely still need to get! Congratulations

[quote user="newbeo"] I am loking to buy my first B and O, looking at the beocenter 8500, 9500 or 9300, any ideas as to whcih I should go for? Thanks [/quote] 9300 has an inferior tape deck, but if you don't plan to use it much (or not at all), the rest of the machine will be more serviceable, and potentially quite a bit newer to begin

Good work, and good pictures! Thanks for taking the time to post them. Seems like your Beomaster has had a pretty good life. Mine have surface rust on the metal parts of the connectors, screws and on the chassis, probably from years in the attic or something. Especially the oldest which is a S290 as well, only 1390 serial numbers away from yours

[quote user="Dillen"] The cost of a CDM kit is typically in the EUR 12 range and that includes packing/postage. [/quote] ...and that is a very reasonable price for not having to hunt several sources, and getting components that are known to be fit for the purpose. I can also testify that attempting the repair without the correct type of C2103

[quote user="Stonk"] I think I've mastered these strings now. I kept re-stringing the wrong way until eventually I got quite good at taking the whole string off and starting again. Now I have it sussed I could probably do each string in about 3 minutes but the problem is that by the time I do it again I will have forgotton how! [/quote

OK, I see what you mean... But the muting signal is taken directly from the output of the integrator op-amp, while there is still T9 before the signal reaches the coil. It might be useful to observe the voltage/current across the coil, but you will need a scope or an analogue meter for that to make any sense. And I'm still very suspicious about

As far as I can see from the schematic cut-out, the the muting relay circuit doesn't care about what speed the integrator works at, it just trips at a certain voltage.

[quote user="chartz"] So how do you analyze the role of C9 then? [/quote] I have no idea of the specifics of this Beogram, but that is a pretty standard integrating amplifier constructed around an op-amp (a lowpass filter of sorts, if you wish). C9 and R58+R61 determine the time constant, while D12 makes it shorter for the other direction

[quote user="burantek"] B&o 3D TABLET! [/quote] Now I start a new thread asking about if this is true, somebody else will ask for pictures, somebody else will draw them and post them in another thread which turns into a discussion on Beoworld's integrity, while in yet another thread people are angry because nobody tells them a price
