Gabster TD1 Manual

All power supplies must be Temporarily fused with a 100 Milliamp fuses, with no Grounded negative. If Using UCPures Change the Fuses to 100 Milliamp
a PSU with a negative connected to ground will cause shorts and issues.
Power the board on a bench without TDA Chip
and no Ufl it should behave like this Video:
Check soldering for over spills shorting 2 adj pads can possibly short power
Check for missing solder joints
Test all UFL Connectors + and - and test for shorts as well
Test power supply 5v and 15v leads with a Ohm meter for shorts
Connect to a cheap Amp/speaker setup first to avoid distroying your system
Run the streamer, play a song then power the board and then Adj DC offset
Turn Volume down prior to powering Dac
Set Monitor Pi pro to FIFO continious clock if possible
If using Ian's I2s to PCM converter make sure Jumper is set to JOB.
Make sure you have the correct Voltage to avoid under voltage humm.
Make sure all wiring and setup follows your Local safety guidelines.

Solder Bottom Parts First
Solder Opa 861 before surrounding parts. Watch for dot (Pin1)
Tantalum Caps are polarized wider end is - Circle on PCB is -
Make sure to watch and Fix C27 + pad error Video Not needed for Ver 3.3 or higher
The soldering iron tip must be smaller than the pad.
Use flux, especially on difficult and small pads.
Measure each resistor, open 1 pack at a time to avoid mixup
Use color coded wires to avoid catastrophic reversed polarity
Watch videos specially how to solder small Components one
Watch for shorting Adj pads like Tantalum caps and Resistors
Use visual inspection and a magnifier to check all joints.
Do not heat the support pins of the RCA connectors for more then 5s as they will overheat and rise. Heat the board pad not the pin. If that happens, heat and push it down.
