762 mA |
1 |
Amplifier wiring together in
common channel. |
2 |
837 mA |
2 |
Amplifiers for each branch are
wired in series; amplifier wiring from interface board is separate.
Problem with short on -5 V supply on assembly. Fixed by
loosening interface board screws, tapping, but actual cause is unknown. |
3 |
827 mA |
3 |
Amplifiers have separate wires
to interface board, but share common channel for each branch. Gain
shapes match well. |
