Repair attempt TC-Electronic Nova System: DSP Audio (guitar)
<< < (4/8) > >>
nilton:
Thank you so very much. Time to go hunting for a used one. IMO the Nova system would be be the perfect companion for a lots of amps having a fx loop including the new BluGuitar amp1. And as it seems from your pics and description the mod should not be to hard to make. I would believe that The larger connector is for the analog signals and the smaller empty one is for data transfer for parameter change. Maybe I2C or SPI.
One more question, I suspect the Line input jack is a breaking type since it disconnects the analog unit as i understand. Can you confirm that?
obiwanjacobi:
Yes, it looks like there are three NC contacts that open when you insert a jack. But that should not matter as long as the drive board keeps working - haven't reverse-engineered that though.
nilton:
Thank you kindly for your info. I'll keep you posted as work progresses

Do you have the power supply specification? I assume you already checked against that...
obiwanjacobi:
I do not have any specs for the supply. But it does not seem to mind the load at all. It's a switching power supply.

I am currently waiting on some SMD soldering supplies to properly clean up the board now that I have desoldered the two chips that got really hot. I also have to restore one or two SMD C's that I knocked out of place while desoldering the chips.
When I got the board clean I will measure the current again.
