I just won a curry Beolit 600 for 42 euro. It has a boken antenna but looks in good condition otherwise. I bought it for the curry panels and for spares because my black Beolit 600 has a slightly damaged bottom plate (broken plastic foot). Maybe I will try to restore both units if I can find a spare antenna. Are these available?

I'm interested in this too, as I have a Beomaster 1100 that blows the 0.39 ohm resistors in one channel. Are the BD651/BD652 usable? In that case I'm going to stock some up, as they are cheap and readily available now. Any modern/common equivalents to the other transistors?

[quote user="jrantala"] One peculiarity of this design are the output stage driver darlingtons (2TR21 and 29, MPSA13), which are bend down thru a hole in the PCB to a lump of cooling paste. looks like an original feature, but never seen anything like it before! [/quote] I'm wondering this too. I'm familiar with potting two transistors

1300 kr i utropspris för ett par. Ser ut att vara i OK skick.

I bought the rings for my CX50 and CX100 at Good Hifi. I refoamed all six woofers with no trouble whatsoever (see separate thread with pictures). The speakers still work fine. I haven't tried rings from other sellers though.

Well, the CX100 has the same tweeter but two bass/midrange drivers instead of one. I have both and the CX50 does indeed sound a bit brighter. The CX100 has the best balance of the two, in my opinion. But remember that God created bass and treble controls to be used.

[quote user="Agent00soul"] I looked and measured some more: There is a 4066 (IC 107) that mutes the output signal and this is controlled via two diodes: D107 mutes it during stop only and D106 mutes it during recording and record-ready (signal labeled "record silence"). Why should the output be muted during recording? It seems that

[quote user="Agent00soul"] After doing some more testing, I have identified ine problem: There is no monitoring during recording. So if you record from the aux input jack, you can't hear what you're recording. I have followed the signal on the schematics and it looks like the input signal should be routed to the output during recording

And check all supply voltages.

[quote user="Agent00soul"] Now I have installed the belts Martin sent me in the Beocord 5000. I'm happy to report that this sems to have cured all faults with this deck. As far as I can tell, it now functions exactly as it should. Some trimming might improve it even further but as it is, it sounds good recording new tapes and playing back
