I am sending my 9500 for repair and restoration soon.  I have been talking to the tech that is going to do the work.  From having listened to many B&O owners over the years, i have constantly heard that in older vintage products we  should replace all the caps.  The tech told me that he only replaces the most important caps and will not replace them all.  

What I thinking is that if I am going to bite the bullet and spend a ton of money on this system, I want it spend the money now and be done with it. I don't want to have to send it back in two years for something else especially to recap the ones he didn't do and they leak. 

So, my question is: How many caps are there on a BC 9500?  Are there that many that the tech does not want to change them all?

I was also told to change all the Trimmers as well.  What is a trimmer?  Never heard of that before.

 

Any advise, suggestions,help would be appreciated.

 

Thanks

Thomas

It's pretty undoable to replace all capacitors. That's a huge amount on different boards. Probably unnecessary also. Trimmers dito. Due to the tolerance of the caps it will be needed to readjust some boards, which I doubt your technician is able to do, like adjusting bias etc on the tape board section.

Things that will need attention will the power supply boards( the bigger caps can leak sometimes, not always), amplifierboard (with a new relais), socket board, decoder board cd-player, upc board with it's few caps/backup battery, tapedeck with new belts, glass panels with a thorough cleaning (be very careful with the paint on the panels when you clean then for refitting them with new tape, new belts for the doors and probably overhaul for both motors with internal oxidized contacts (less torque). The cords for the doors should be cleaned or replaced. This last few things just only to achieve a smooth movement of the doors. Make sure these are aligned nice and properly when the panels are removed and put back again.

Only this above mentioned list of things can easily take almost a day of labour for an experienced technician.

Beobuddy,

 

If you were sending off your 9500 what would you ask the tech to do?

 

THanks
