The final boards to be recapped in the Beomaster 8000 that I am currently restoring were the FM tuner boards. Here are some impressions of this effort. This shows the boards with the original capacitors:
And here after replacing all electrolytic capacitors with 105C grade Japanese units:
With these boards it is especially important to clean the contacts between the boards and coat them with DeoxIT. I had several cases in the past where one channel did not work on the tuner, which could directly be traced to a contact issue between these two boards. After I put everything back together I tested the Beomaster and everything works fine now!
This concludes the recapping of this Beomaster. On to the displays and the uProcessor boards. On into the heart of the dragon...;-)
Well, i have got a question here.
ReplyDeleteCould bad caps on the tuner board be the reason i get no signal of any radiostation at all? Just static.....
