Hi All
I have purchased a non-working SX690, same as the SX680 but different dial face (I think).
A really nice looking unit, well built, no idea what they sound like, but i got it to try and fix up without going for the shotgun approach. I know the STK-0039 modules are considered a weak point of this unit.
I just wanted to request some help with this and hopefully with your patience and guidance i can bring this unit back to life. I will then gift it on to a friend who will enjoy it.
So first things first. I took it apart and deoxed all the switches and pots.
Next thing i suppose is to try and get the voltages from each STK and post them here.
To do this, do i just take each reading from the pins on the underside of the board with one lead of my meter connected to chassis of unit, the other on the 0 9 8 and 3 2 1 pins?
One thing i did notice straight away is that the schematic shows 2 fuses beside the stk modules which are not present in my unit?
I would really appreciate some help with this, this will truly be the first foray into actually using some level of diagnostics in fixing a unit. Thanks in advance folks
