BUSTED!!
Hi Mark and other AK gurus,
I recently picked up an SA-9800 locally for pretty cheap. Tested it before buying and it plays music but with the usual scratchy pots, etc.
However on closer examination after bringing it home, I found that the music is not as "clear" as is normal for the 9800. Also a few other issues caught my attention:
1. When the unit is powered on, fluoroscan meter / pilot turn on as normal.
2. Music starts playing immediately (literally as soon as i flick the power switch on!)
3. HOWEVER, there is no protection relay click!
Upon opening up and taking a look, I found several signs of non-factory soldering, use of very cheap quality (single thin strand) wire, etc.
While the amp does play music, Im concerned that the previous repair job might have included bypassing the protection relay circuitry which is needless to say, putting the amp at risk overtime I use it.
Any advice on where I should start looking to investigate this issue?
Thanks in advance.
