I bought this amp knowing it needed work. There is a fair amount of ground noise or hum (not sure if it is a ground issue) when something is plugged into the inputs.
If I don't have anything plugged in and turn up the channel volume and master volume all the way, the noise is way less.
I rewired the inputs in the schematic below because the wires and resistors from the stocking wiring broke, I'm just wondering if I wired it right.
The input jacks are TRS.
Looks like, give the schematic, that the HIGH input is supposed to have the TIP going to one end of one of the 68k resistors, with the RING and SLEEVE of the HIGH IN going to ground.
The Low Input TIP goes to one of the other 68K resistors and the RING going to the TIP of the HIGH In, and the SLEEVE going to ground.
Is that correct? I'm wondering if I wired it wrong and that is why I'm getting this hum.
*** Please note there is a cap that is highlighted in the linked picture, ignore that**
Thanks.
