Hello, working on a T1000-1bdcp. Power supply was smoked so I replaced power supply mosfets, output mosfets, 2 transistors on ps card, all three rail caps, and r200 on bd card. The amp powers up and plays but is drawing 3.6 amps at idle. The amp has a small speaker pop on turn on and draws less current when gain is turned up and as gain goes up I am getting a whine in speaker. Any advice? I have swapped a known good ps card and bd card with no changes.
There should be essentially no voltage across the speaker terminals. The voltage isn't really critical since you're not going to drive audio into it. This is just to test for noise on the output and maybe just a few volts of audio.
If you want to drive audio into a speaker, you can connect two polarized caps in series, negative terminals connected. Positive terminals to ± speaker terminals. 22uf@100v would be ideal but you can use almost anything above 22uf and near 100v if you intend to drive audio into them.
