I have a G99X that's been waiting on the table for a few months now.
Poor fella got a bruise or two during shipping and did not play very happy from the first minute. After a little persuasion, he started singing happily.
Then I tried to dial in the offset and bias but I slipped and touched the wrong pins and that's when I learned the smell of defeat. There are no words to explain how shitty I felt at that particular moment and for the rest of the day.
I had big plans for my G99X. I read so much about D11 II and since they share so much I wanted for him to grow up one day and be like the older brother. In the meantime, I got AU-717 playing in the background.
Long story short, I'm making a list of parts to be replaced. Here are my doubts and thought:
1. Sansui replaced PS caps with orange film caps. There is a lot of these on almost every board. Should I replace them and with what. I could go with C0G(easy) or PS(hard). What would be your call?
2. Is there any need to increase the capacitance of power supply caps?
3. Some of the D11 II owners did a resistor upgrade to all metal film and I'm not sure that I'm ready to go this far. What PCB would benefit the most from switch to metal film...Control, Amp, Driver ...?
Here's a top view of mine G99X. Underneath it is D11 II (recaped) just for reference to see where did Sansui save some money.
Here's a D11 II(restored) from rayner06. Hope he doesn't mind borrowing his photo.
