Some of the PCBs are easy to get at, but the interconnects are all soldered wires, no jacks or plugs, on my BC 2000 RtoR I could easily take out all the PCBs. In the lower left corner you can see a double lever system for the switches, all of these needs cleaning and lubrication as most of them moves slow and hard.

The ROE caps all looks good, no leaks found until now.

The wood fame is cracked in the back right corner it will need some work, but the rest is OK, the diagram was in the envelope

The whole "joystick" mechanism moves hard and slowly, very old grease and dirt.

The switch assembly, someone put back the Left speaker button upside down

The buttons off on the switches one can see the copper plates that are supposed to sit on the top of the double levers.

As I had to dismantle the joystick mechanism I had to take the slider PCB out I changed the ROE and red drop caps, I may go on and change the black drop transistors too the sliders are a PIB, one cant open them for cleaning.

Now one question, the motor has a very big 130 V 8 uF capacitor, it is attached to some serious anti vibration support it looks OK and I will check it with a meter.

With what can I change it, everything I find in 8 uF is tiny like 10 mm diameter and 20 mm long.

While I involved myself in the repair of some B&O equipment (not being succesfull sofar), listening to "vintage" music played back on a BC 1200 (R2R), I came accross this thread.

A couple of weeks ago it all of a sudden stopped playing, whereas Rewind and Fastforward still function as they are supposed to do.😢

I take the opportunity to ask here, in view of the clear pictures, for advise as to what might cause this problem (or should I start a new thread?)

 

 

 

 

I can get these axial caps from mouser USD 1.50 Vishay but very small to the physical size, as in your link, will a small one like that do.

I didnt get that far yet, but if I remember right there are various switches and other components involved in the play circuit, it may be a simple thing, but considering the age of the BC capacitors and some transistors may be in need of renewal. I intend to change all electrolytic and red drop caps some transistors and trimmers where needed. Follow the thread to see what comes out.

Caps have become a lot smaller over the years as we both know. But the real question is it a motor cap or a standard general purpose cap. might make a difference. Possibly a big difference. Is the cap polarized for example.
